1971 Chevrolet Camaro Powered by a ZZ502 Big-Block

Internet Score: Right place, right time eBay find brings home this second-gen Camaro

1971 Chevrolet Camaro Powered by a ZZ502 Big-Block
Most individuals have heard the phrase “right place, right time” used to describe that moment when something really good happens. Sometimes things occur and their impact isn’t realized until much later. The 1971 Camaro seen here is the result of a “right place, right time” situation for Marylanders, Don and Karen Moretz. Over the years, both had invested a fair amount of time trying to find the right project car, but always came up short in their quest. As Don explains, “Since we live on the East Coast, everything we saw had rust issues.” At some point, they stumbled across a fully documented 1965 Nova Sport Coupe that was in pristine condition with only 16,900 miles on the clock. Powered by a 194-cubic-inch inline-six, the diminutive Chevy II didn’t exactly scream performance. It was, however, the ideal foundation for a killer street rod. They took the plunge and bought it, but as time passed, an issue of conscience arose. That much originality created a real dilemma for Don. He points out, “It was so original that I couldn’t bring myself to make any changes to it.” While they inherited a really nice cruiser, it didn’t get them any closer to fulfilling their goal.
Unrelated with anything to do with cars, Don and Karen are also die-hard football aficionados. “As avid Baltimore Ravens fans, we were looking for season tickets,” Don states. “Karen was looking on eBay and saw someone offering to sell their PSL (Public Seat License) for four seats at the M&T Stadium.” In Maryland, you need to have a PSL before you can buy season tickets. The opening bid was $1,995 for four PSL licenses, so for seven days they tracked the auction. Near the end of the auction they were surprised that no one had bid, so she placed a bid for the opening amount, which proved to be a winner. This was a “right place, right time” moment, but you might be asking, what does this have to do with a Camaro? Please read on.

By the fall of 2006, the Ravens were a team on the upswing, so Don decided to test the waters. “They were doing really well and I thought that it might be a good time to see if there was any interest for someone to bid ridiculous money if they (the PSLs) were offered up,” he says. EBay was the best means to sell all four PSLs. The starting bid was a hefty $14,500, and within 15 minutes of posting it—to his surprise—someone had placed a bid. He recalls, “that was only the first day of the auction, and I had posted them for seven days, so we watched the bids slowly creep up each day.” In the end, someone had dropped over $20,000 for all four licenses. Are you beginning to see where this is going?
With a nice pile of newfound cash in hand, it was time to resume the search for a suitable car. Don was a fan of second-gen Camaros, so that was what they focused on. As was the issue before, most of the cars they looked at were described as being in “excellent shape,” which was open for broad interpretation. EBay was again the place that got the job done. Don found this particular 1971 in Georgia, but was apprehensive about bidding for fear of buying a cleverly disguised rust bucket. While the auction was still live, he asked for more photos and information, and also hopped on a plane to see the car in person. It was everything that was claimed in the auction, and he was the eventual high bidder. The money from the PSL sale just about paid for the purchase of the ’71.

The Camaro was perfect for what they were planning. While it was a real 396 big-block SS, which outwardly appeared bone stock, tucked in between the fenders was a fresh Chevrolet Performance ZZ502 crate engine, so the originality hurdle wasn’t an issue. It didn’t take long after bringing the car home that the parts swap began, and as is the case when adding aftermarket parts, having the right reference material is half the battle. For that, Don relied heavily on the content and advertisers in Super Chevy and Camaro Performers magazines.
The first change on his list was to give the ’71 the right stance and an improvement in ride quality. Don points out, “I wanted the car to have the look of an off-the-line Super Sport, but with all the tech changes to improve on how the suspension was originally designed.” Since it was rolling on factory Rally wheels, those were the first to go. In their place he installed a set of Billet Specialties Vintec 17x7 wheels wrapped in Nitto NT555 Extreme ZR 235/45ZR17 tires at the front and Billet Specialties Vintec 17x8 wheels wrapped in Nitto NT555 Extreme ZR 255/45ZR17 tires at the rear. The new wheels lowered the car, however, it still wasn’t low enough. That feat was accomplished with the installation of adjustable QA1 coilovers at the front and Hotchkis lowering springs at the rear. Stopping was also enhanced with a set of SSBC Big Bite cross-drilled and slotted rotors and SSBC calipers. The end result was a 2-inch drop in ride height and enhanced ride quality.

Under the hood, aside from the ZZ502 mill, the rest of the hardware had that factory fresh appearance. While the plan was to leave the engine unmolested internally, it did need to be dressed up. Crowned with a replacement Edelbrock Performer manifold and Performer 750 carburetor, the only thing that he did was massage them visually. Also added was a K&N air cleaner assembly and Billet Specialties Profile polished aluminum valve covers. The engine compartment received additional billet pieces, like the alternator, A/C unit, and a set of Fesler billet hood hinges that he found under the Christmas tree. There was plenty of bling being added to the engine compartment, but he says, “As good as the engine area was beginning to look, I was tormented by the shape of the inner fenders.” A friend suggested that carbon-fiber replacements would look great. The problem was that no one was offering them for second-gen Camaros. As luck would have it, he stumbled across a post in a forum announcing the impending availability of said pieces from Anvil Auto. “I placed an order and Santa came in a big brown truck on Christmas Eve,” he exclaims. Other carbon-fiber items from Anvil Auto added were fender supports and a closeout panel for the top of the Be Cool aluminum radiator.
The ZZ502 is backed by a TCI 700-R4 transmission that delivers power to the stock GM posi rear. Don upgraded the exhaust to give the Camaro a throatier sound. He added a set of ceramic-coated Hooker Competition headers that dump into a set of 3-inch Flowmaster Super 10 Series stainless steel mufflers. For even louder tunes, he added QTP electric cutouts.
The paint that came on the car was impeccable by most standards. However, knowing what was under that paint was equally important to Don so he had the car repainted with the same black and white stripe combination. Keith Edwards at K&K Customs in Aberdeen, Maryland, performed that task. He laid down the slick PPG Deltron basecoat/clearcoat bath, giving the ’71 a fresh, wet look to go with all the added billet items.

Much like the rest of the car, the interior was in equally nice shape, but rather stock looking. While not wanting to deviate much from that factory appearance, he does point out, “The interior was in good shape, but with all the improvements made to the exterior and engine bay, I felt that a refresh was necessary.” Those changes included the installation of new carpet, along with a healthy dose of Dynamat to keep things quiet and cool. The seats were also reupholstered, and as was the case under the hood, a few billet items like window cranks, striker bolts, and vents were installed.
For all their work, Don and Karen have had a ton of fun putting this car together. They show the car at many local and national events, yet their most prized wins have been at the Super Chevy Show in Petersburg, Virginia. The Camaro has been recognized as a class winner two years in a row. By his own admission, it has been expensive to put the ’71 together, yet being in the right place at the right time and finding a pile of unexpected cash has certainly made the sting less painful.

Big-Block Powered 1970 Chevrolet Chevelle SS

Hard Candy: Function Over Form and a Pragmatic Approach to the Car-build Story

Big-Block Powered 1970 Chevrolet Chevelle SS
Everybody loves their cars the way they are, don’t they? Yeah, sure they do…until the next inspiration becomes a blast broadside. Yeah, too many magazine articles, too many bitch-forums, too much mean-spirited rhetoric spewed on the “social media” often hurts more than it helps the cause, coercing changes that were never part of the original idea. Time is the enemy, too. It’s like writing a story and then having too much time to hand it in; the longer it hangs around, the more changes you’ll make and make until the sun burns out. Best to button it up timely and kick it out the door.

Some hot rodders work from an entirely different perspective. They strive to recreate an entire era…or just a moment. Sophomoric silliness gives way to life’s hard facts. Adolescence is abandoned for the path to manhood. The transition is gritty and resinous because no two individuals ever see the same thing the same way. At 33, young Ben Chase is experienced. “This car was the first one I ever purchased. I was 16. I built it according to my vision of how I always wanted a Chevelle; clean, simple, old school, with a carburetor and a manual transmission. Yes, many friends have helped along the way.
“I think the unique thing about this car is that it isn’t an ultra-modern build. It doesn’t have a custom interior; it doesn’t have 20-inch wheels; it doesn’t have custom body modifications. It’s just a simple, clean car. I wanted a timeless, cool hot rod.”

Impetus came from the 1993 movie “Dazed and Confused.” The protagonist drove a black 1970 SS Chevelle. Ben wanted to pattern his Malibu in a like manner, and was urged immediately when he damn near crashed the first night he drove it because he didn’t realize how poor the drum brakes were. Suffice that Ben tooled the original small-block for a while and when he no longer felt that excitement wriggling in the pit of his stomach, he put a 468-inch big-block under his foot. And so it went for a while.
Then Ben called in the shock troops. Keith Zimbauer did the metal fabrication, welding up the transmission tunnel and mini-tubs, smoothing the firewall, constructing the exhaust system and putting patch panels in the front fenders. Vic DeLeon, Jr. did a lot of the wiring and finish-work, plumbed the fuel system, did the seat covers, and got the motor ready to fire. Once on the rollers, Vic, Sr. at DeLeon Dyno Service in Santa Clara, California, put the magic wand over it.

The object of his attention was the 496 in the Chevelle’s maw. Larry Klein at Speed Merchant (San Jose) had performed the machine work and the heralded Paul Caselas at Dyno West assembled the bullet with a forged rotating assembly, AFR 325 cylinder heads, a Crower hydraulic stick (0.636/0.659, 253/260 at 0.050-inch) and Edelbrock double-row timing gear, Moroso 7-quart wet-sump, Melling pump and peppered it with ARP fasteners throughout. The 950-cfm Holley sources fuel from Race Pumps mechanical system. The ancillaries include a Powermaster alternator and a Be Cool aluminum core. Ceramic-coated Lemons headers dump into a 3-inch stainless steel Magnaflow system incorporating an X-pipe and genteel Magnaflow mufflers.
Torque transfer begins at the 11-inch Kevlar/organic clutch disc and a QuickTime bellhousing accepts the Tremec TKO600 five-speed. Steve at South Bay Driveline in San Jose, provided the 3-inch diameter prop shaft that hooks to a GM 12-bolt. Keith at Z-Fab Off-Road in Rapid City, South Dakota, buttressed the axle with 3.73:1 cogs and a Detroit True Trac differential.

Regardless of the owner’s fealty to function, the car’s setting represents form undeniably. Though there are several methods to set the stance, Ben stayed completely mechanical, outfitting his A-body with B-body spindles (1-inch drop), Global West negative-camber controls arms with Hotchkis springs (1-inch drop), non-adjustable Bilstein dampers and a Hotchkis 1 3/8-inch anti-sway bar. He set the rear end up with Hotchkis coils (1-inch drop), boxed lower control arms, Bilstein shocks and a 1¼-inch anti-sway bar. One look at Ben’s Big A says he got it right. On the side of that critical friction quotient, he gathered Baer 13-inch brakes all around and he capped them with shining 17x8 and 17x11 Billet Specialties hoops holding 255/40 and 315/35 Pirelli P7000 skins.
Things in the office space are pretty much like they were when the Chevelle cleared the assembly line 45 years ago. But certainly there are small departures: the Grant GM Corvette Tri-Spoke steering wheel, the minimal audio range set up by Vic DeLeon, and the staid vinyl upholstery put there by Top Notch in San Jose. There are no distractions, nothing superfluous simply because function guys don’t need anything more. If there were dollars with wings on them, they would only be for mechanical advantage.

As for the exterior, the theme was make it straight, make it clean, and maintain the vibe original, which Michael & Company, Inc. accomplished without fail. “At first, I thought I wanted a black car with white stripes, just like the movie, but realizing what bodywork and upkeep would take on a black car, I changed my mind on the color,” Ben opined. The stripes are not white and the livery is Volkswagen United Grey Metallic.
Any regrets, anything he would have done differently? “Since I’ve gotten older and my tastes have changed a bit, I think I would have gone milder on the motor. The [big-block] engine keeps getting less and less user-friendly. If I were to do it over again, I would put a mild fuel-injected motor in the car, maybe an LS3, and definitely air conditioning.
“These projects that are supposed to take a year or so to complete inevitably snowball into five, ten or more years, but the car is literally the embodiment of a vision I had for it many years ago. I had a picture in my mind of its appearance, its attitude and couldn’t be happier with the result. In the end, it didn’t turn out being the Dazed and Confused car, but I’m more than okay with that. To quote Matthew McConaughey’s character, I think the car came out ‘…Alright, alright, alright.’”

Clean, Mean Big-Block-Powered 1970 Z28 Camaro Street Machine

Part rejuvenator, part instigator, all specific

Clean, Mean Big-Block-Powered 1970 Z28 Camaro Street Machine
Though not a Camaro family by any means, we were privy to two of the great ones when they were new: a 1967 RS/SS (350ci) and a 1969 COPO 9561 (427ci). We loved the sleek symmetry and the oomph the extra cubic inches that the new 350 provided the first one and certainly with the low-production exclusivity and big torque of the other one, but we didn’t much care for its styling. Thought it was too far removed from the originator and never really got used to its lines.
We knew from nothing about handling strength, or the lack of it, which was probably a good thing. We didn’t become members of the OOC (out of control) club and wind up in the weeds upside down or something like that. We were too chicken to do anything but pound it in a straight line. Besides, racetracks with corners were for sporty car types who were then typified by a pipe, pimpy moustache, and newsboy cap, a stereotype we avoided like the Black Death. No, we flicked Lucky Strikes, wore ridiculous sideburns, and wore even more ridiculous plastic loafers.

But when the 1970½ Z28 came on line in the winter of 1969, we knew they’d gotten it right. Better ride, a stronger, torquier engine, and looks to go out and commit murder for. Overall, it was a very sweet dream.
Mike Fillipini had a similar out-of-body experience.

“I purchased a new Chevelle SS 396 in 1969. In 1970, I accompanied my brother-in-law to the dealer when he bought a new Chevelle. One of the cars in the showroom that day was a red ’70½ Z28. That image of that car burned into my memory. Thirty-five years later, I finally bought one,” said the union electrician. He found the car in March 2005, where so many of us do these days. It wasn’t the Want Ad Press, but in the comfort of his own home on eBay.
According to him, “It looked pretty good from 10 feet, and I was satisfied with it until the fall of that year. The car had a loud geardrive and a solid cam that I did not like. The motor had way too little vacuum so the brakes weren’t very good. The body had some issues that had not been properly addressed, so I disassembled it to have them fixed and to get the car painted.”

The project consumed about two years—a mere speck of time compared to others we’re intimate with—due in part to a squad of faithful family members and friends who donated precious time as well as moral support and a kindred spirit. The dedicated cadre included wife Mary Anne (moral support and understanding), Vince, Tony, and Dan Rolberg, and Luke Smith at Modern Carriage Werks in Bridgeview, Illinois (paint and body), Kevin Lawrence (a ton of advice), and nastyz28.com (for information imparted).
While the car was in various states of undress and its members easily accessible, Mike addressed the chassis with 2-inch drop spindles, 13-inch Baer discs, tubular upper and lower control arms, and QA1 adjustable coilover shock absorbers. He is most appreciative of the Hydra-Tech hydraulic brake assist system and even more of owner Paul (“he’s extremely knowledgeable and great to deal with”). At the rear, 12-inch Baers and slapper bars suffice until the coveted four-link and coilover suspension is put in place.
1970 Big Block Z28 Camaro Engine
Since any car in our world is virtually defined by its engine, especially if you came from the muscle car era, nothing less than a big-block would ever do. By Mike’s good fortune, his Camaro already had one. Founded on a Chevrolet steel crankshaft, the Rat’s 427-cubic-inch short-block sports a balanced rotating assembly and 10:1 TRW forgings. ARP studs secure the ported, closed-chamber square-port iron cylinder heads. The basis of the oiling system is a Melling pump and a Milodon 8-quart sump.
Mike satisfied his camshaft jones with a COMP CB XE284H hydraulic roller (110-degree lobe separation, 284/296-degree duration at 0.050-inch, 0.574/0.578-inch lift) that jigs the valves with cigarillo-fat 3/8-inch pushrods. He put it to bed with a Cloyes double-roller timing chain, sealed it with a GM timing cover, and mounted a Weiand aluminum water pump directly ahead. Engine cooling begins with the Harrison four-row copper core.
1970 Big Block Z28 Camaro Carburetor
For the upper respiratory system, Mike retained the Chevrolet aluminum intake manifold and completed the fuel system with a Holley electric pump, an 850-cfm Quick Fuel Q-850 carburetor, and K&N filtration. An MSD 6AL box, coil (both of them relocated beneath the dashboard), and Pro Billet distributor supply the fire. On the back end, ceramic-coated Hooker Super Comp headers with 2 1/8-inch primaries purge into a 3-inch exhaust system fixed with a crossover pipe and animated by Flowmaster 40 mufflers. Rather than running the pipes all the way to the bumper, Mike abbreviated it with turn-downs.
As it would have back in the day, the engine supports only a power assist for the steering and an 80-amp alternator. Air conditioning was not available on any Z28 and has not been retrofitted here, nor is there power-assist for the brakes. Power estimations are 525 hp at 6,500 and 500 lb-ft at 6,500 rpm.
Torque is processed by a TKO 600 five-speed and managed by an 11-inch Centerforce Dual Friction clutch assembly enclosed by a Lakewood blast shield. The complete swap kit included a 3-inch diameter driveshaft. And this piece just wouldn’t be right without a Positraction-equipped 12-bolt holding 3.73:1 gears and Moser axles.

What about the Camaro’s “face?” What did Mike do to individualize it? He says the unique feature of the Z28 is its paint. Modern Carriage Werks assumed the project, smoothing the skin and applying the Sherwin-Williams Spectra Red base and clearcoat. “It has a bit of diamond dust in the red that’s only noticeable under the sun or a street light. I get a lot of comments on it,” Mike replied. To bump up the go-fast image, Modern included a VFN fiberglass bonnet with a 4-inch cowl. Lo-Ko Performance Coatings in Oak Lawn, Illinois, did the powdercoating. When it came to the critical choice of wheels and tires, he accentuated the corners of the car and completed its perfect stance with 17x7 and 17x8 Torq-Thrust II rims and 225/50 and 275/60 Nitto 555s.
In the security of the cabin, Mike finds comfort, confidence, and support in vinyl-clad Corbeau buckets, ACC carpeting, and a Hurst shifter. A custom-built instrument panel holds Auto Meter Ultra-Lite gauges. When the sound of the engine has saturated him, he turns to the Pioneer Super Tuner head supported by Pioneer front speakers and coaxial horns in the rear.

Mike’s produced a careful, detailed package underneath the floorboards that’s just as clean, neat, and meaningful as the exterior. “I’ll be retiring in the next year or so, and it will be time for another build, but rest assured this Camaro will be with me until my grandson turns 16, and that’s not for another 11 years. For now, we take it to shows and cruise nights and just put miles on it. The car runs well, stops good, handles decently, and is a freakin’ blast to drive!”
Mike says that his most memorable experience wasn’t confined to one particular area of the car but rather building the whole thing. It has proved an excellent therapy for stress and might even be rejuvenating.
“I really have not done much work on cars outside of general maintenance for the last 20 years. I was surprised at how much I’d forgotten since I raced my Chevelle in the ’70s. It ran mid-12s, which was pretty decent in those days. Luckily, I have some smart friends. Best part of it all? When I’m in the garage working on it, I feel like I’m 21 again.”

1967 Chevrolet Camaro - There’s No Place Like G90

Fate Made This ’67 Scott Peterson’s First Car; The Skills it Inspired Made it First-Rate


1967 Chevrolet Camaro - There’s No Place Like G90
My first car. From an enthusiast’s perspective those three words probably carry more weight than the million or so others around them. Even if your first was a turkey, chances are you’re still pretty fond of it. It meant you never had to rely on anyone else to go somewhere. In fact, some peoples’ first car put them on their path, so to speak.
For our purposes, Scott Peterson’s path began in 1986 with a ’67 that started life with six cylinders and half as many speeds. “It didn’t take long for me to pull the motor and transmission and put in something bigger and better.” His weapons of choice: a built 327 and a T10. Rules of the day dictated Centerlines and Radial T/As—a combination that got him through high school in style. “Then I entered the mainstream,” he continues. Sadly, that meant the Camaro sat on the sidelines. A dirt car Scott bought in the late-’90s needed power so the 327 was liberated from the Camaro. Then it sat some more. “But I refused to get rid of it.” Then, in 2004, the mechanical interests kindled by the Camaro 18 years prior inspired Scott once again. He and his wife, Julie, founded SDS Machining. But this shop doesn’t just machine parts; it makes ’em on a host of CNC-operated tools.
Inspired by his new toolbox’s potential, Scott did the same thing you and I would: he started dreaming up parts. Reinvigorated, he dusted off the thing that started him on his path. Only this time he did all the things he never could’ve dreamt of before.
1967 Chevrolet Camaro Front Hood
Wade Delco and Ryan Winkler with help from Dale Wickline, Ryan Delco, and Dave Harris established the car’s racing theme with a 10-point ’cage made from A513 seamless tubing. “We knew the big-block we were having built would twist the car up, so a rigid foundation was important,” he explains. Rather than finish the chassis with universal production components, Scott employed his resources to tailor it specifically for the application. “All of the suspension was designed by Wade and Ryan and fabricated by them or machined by the team here at SDS Machining,” he indicates. The front package consists of tubular control arms, knuckles, and steering arms designed to optimize the geometry. A triangulated four-link system locates a 9-inch-style Moser housing. RideTech’s Level Pro system and 1000- and 7000-series ShockWaves optimize the vertical spring force for the ideal ride quality and stance for any occasion. Antiroll bars and custom-fabricated endlinks optimize the lateral spring force for ideal handling.
The 4.6-inch-bore Dart Big M block and the 4 3⁄4-inch stroke Eagle crank swinging in it more than hint that this is no ordinary engine. Nye’s Automotive in Muncie, Indiana, made the most of every one of the engine’s 632 cubic inches by endowing it with an aggressive COMP Cams mechanical-roller-tappet cam. It’s a stick that boasts 313 and 322 advertised duration, figures sufficient to cripple most smaller performance engines at speeds just short of their redline.
Engines as big as this one breathe deep, as do the 385cc intake ports in the Brodix Head Hunter cylinder heads. The flat-top Diamond Racing pistons yield a 10:1 static compression ratio. Though he used a Quick Fuel P-series 950-cfm carburetor on an Edelbrock Victor manifold for the time being, Scott equipped the 20-gallon Fuel Safe cell with an Aeromotive in-tank A1000 fuel pump in anticipation of a future EFI system. The monster snorts through 2 3⁄8-inch headers, a 4-inch-diameter exhaust, and oval mufflers fabricated by the build team at SDS Machining. Despite its pump-friendly nature, the engine churns 804 lb-ft of torque at 4,800 rpm and a whopping 811 horsepower at 5,800.
1967 Chevrolet Camaro Engine
One end of the engine drives a March Ultra Drive system; the other, a Bowler Performance torque converter and a 4L85E gearbox built and modified for six-speed operation by Mark Bowler. It shifts by two means: stick by way of a TCI Outlaw shifter and paddle by way of the paddle shifters.
Portland’s Driveline Specialties fabricated the steel driveshaft. It spins a 3.70:1 gear on a limited-slip carrier in the Moser housing. Speedway Engineering provided the 31-spline axleshafts. To give this juggernaut a chance to scrub speed, Scott chose Wilwood’s 14-inch rotors and six-piston calipers. He also used the company’s dual-circuit master cylinder, but took advantage of his company toolbox to make the pedals.
Though extensive, the body modifications throughout the car don’t immediately reveal themselves. In fact, most owe their existence to mechanical necessity. For example, the four inches that Wade Delco and Ryan Winkler extended the rockers make the already low car appear even lower, but that’s actually secondary. The original intent was to conceal the 4-inch-diameter exhaust system and give it a means to exit the car through SDS-machined outlets in the rockers rather than under them.
The fabricated front valance extends lower than stock to match the rockers’ new elevation and to support the machined-aluminum splitter. Extending the valance an inch forward at the grille deepens the opening and restores the nose’s profile. The rear bumper and roll pan enjoyed the same slap and tickle for consistency’s sake. Delco and Winkler shot the BASF Glasurit 55 Line urethane base/clear in a color that a cagey Scott calls G90 Metallic Gray.
Flush-mounted glass hardly bears mention anymore. This does. Rather than conceal the gap between the body and production glass with T-molding as others do, Kevin Batey at Auto Glass Past and Present in Vancouver, Washington, worked with the SDS team to close up the gap with custom glass, a fit typically exclusive to modern cars. Partly to honor the aerospace contracts that made this build possible, SDS had Advanced Precision Anodizing in Troutdale, Oregon, finish the aluminum throughout the car.
1967 Chevrolet Camaro Interior
Prior to delivering the car to Jim Sanders at Jim’s Custom Upholstery in Milwaukie, Oregon, the SDS crew fabricated the interior panels and a steel dash from scratch. It’s a laborious task made even more painstaking by accommodating the 10-point ’cage. The CAN bus architecture ISIS Power uses in its Multiplex system organizes electrical functions by modules installed throughout the car. The company’s Touchmax panel groups all electrical controls conveniently in the upper center console.
Jim Sanders, with help from Stayton Peterson, Scott’s son, finished the fabricated dash and interior panels including the Corbeau LG-1 Wide seats in black leather. The ’cage mounts Schroth three-point harnesses front and rear. SDS machined the dash insert but New Vintage crafted the Red Line series gauges, among them a pressure gauge for the Top Shot nitrous system should Scott wish to inflict another 200 horsepower upon the tires.
Back at SDS, the Camaro got a Vintage Air climate control system and a host of audio components, among them a Kenwood DDX719 head unit, Kenwood amplifiers, two Alpine SWR-T10 subwoofers, and two sets of Hertz ESK 165L component drivers.
Not even the Forgeline ZX3P wheels escaped the SDS touch. The company machined them, submitted the centers to anodizing for consistency’s sake, and laser engraved the center caps with the G90 logo. They measure 19x9 and 20x12 and wear 265/30-19 and 345/30-20 Michelin Pilot Super Sport hides. With the last lug tightened he was done … done for now at least.

But we’re not quite yet done. Scott extends a great deal of gratitude to his wife, Julie, for her patience. “You can imagine this build went over budget and took a lot longer than anticipated,” he says. He also praises the SDS crew, for without its help he admits he never could’ve pulled this off. “A business is only as successful as the people, and we have great, talented, dedicated people,” he says.
Oh yeah, about the car’s name. “People ask what G90 stands for,” Scott admits. “It’s CNC machine code that represents absolute position.” Translation: G90 represents the reference point from which a CNC machine bases all of its measurements and movements. It’s the machine’s homeif you will, the point from which it started its path and it knows exactly where it stands in relation to that point.
As a general rule, old cars take their drivers back in time as they take them to where they’re going. Scott Peterson’s first car takes him more than back in time; it takes him to a special place personally and professionally: G90. You know … home.
