On top, you'll find a pair of AFR 210cc Eliminator cylinder heads, which are box-stock and feature 2.08- and 1.60-inch valves. A custom-grind Cam Motion camshaft sends the valves into motion, while the Jegs 1.5 roller rockers provide a smooth transition from the pushrods to the valve springs. For induction, Preston relies on an Edelbrock Victor Jr. intake manifold, which draws in a mixture of fuel and air through the 830cfm Pro Systems carburetor. A Holley blue pump provides the fuel, while an MSD 6A-L ignition system sends fire to the combustion chambers.
Outgoing air travels through a set of Hooker 13/4-inch headers and into a massive four-inch exhaust system, complete with a Spin Tech muffler. Behind the 406ci small-block is a TH350 automatic transmission, built by Second Hand Power in Memphis, Tennessee. It's operated by a B&M shifter and power application is controlled by a BTE 4,000 rpm torque converter.
Since he built the engine himself, Preston doesn't have an exact figure on horsepower, but the car has run a best of 6.72 at 106 mph in the eighth-mile with the assistance of nitrous. (For you quarter-milers, that equates to about a low 10-second run at about 130.) Future plans call for a fogger system, but the two-stage plate kit will do for now. Brian Dixon wired the nitrous system and the second stage is activated through a digi-set timer that is adjustable in 0.10-second increments. A custom fuel cell supplies race gas to the fuel solenoids when the nitrous is engaged, and rides in the original battery tray.
Preston wanted good looks to go along with fast elapsed times, so when the original paint began to fade, he contacted his longtime friend, Rusty Edwards, for a fresh coat. While the car was in the body shop, Rusty shaved the door handles and all of the original emblems for a super clean look. He then blasted on the PPG materials, mixed in a custom off white hue and followed that with a few coats of clear. The bumpers, side skirts and rear spoiler are from a newer third-generation car, while the cowl induction hood is an aftermarket piece.
A peek inside Preston's Camaro reveals a mostly stock interior, but he's grown accustomed to this environment over the years, so there was no need to change it. He swapped the original seats for a pair of third-generation Trans Am buckets, and installed an eight-point S&W Racecars roll cage, made of mild steel. The dash is all stock, but Preston added an Auto Meter tach, and a Grant steering wheel. He then eliminated the A/C system, as well as the stereo to shed a few pounds.
Over the years, Preston has become attached to his Camaro and doesn't plan to let it go anytime soon. At first, it had the oft-maligned 305ci small-block, and it's now a rather healthy specimen on the track or the street. With good looks and plenty of pep, the '83 Camaro has gone through quite the transformation, but that doesn't mean he's finished with it. Regardless of his future plans, Preston has a fine example of a third generation Camaro, and it will only get faster with time.
