Drivetrain
Three years ago, the 6.0L LS2 was the hot GMPP crate engine. As was Terry's modus, it stayed pretty much stock. For the Chevelle he wanted some of-the-day flavor so he supplanted the EFI system with a GMPP four-barrel intake manifold, Demon 750-cfm carburetor and matching front-mounted distributor/timing cover from Wegner Motorsports. Wegner is a supplier of LS-type NASCAR spec-engines and therefore based on the carbureted system, so in this respect they were way ahead of the curve. The detailed and compact accessory drive is also a Wegner product. Terry upgraded the oiling system with a Street & Performance pan, pump, and windage tray so that the engine would not starve during the high-g corner loading that the car would inevitably experience. MSD furnished the 6AL box to work with the DUI HEI-type distributor. The ceramic-coated header tubes measure 13/4x30 inch and dump into a 3-inch exhaust system. Wegner dyno tested the mild combo at 388 lb-ft of torque at 4,500 rpm and 391 hp at 6,000 rpm. McLeod is responsible for the modular bell housing/scatter shield and companion steel flywheel, clutch disc, and pressure plate assembly that are operated by hydraulic "linkage." The recipient is a Classic Chevy Tremec TKO five-speed conversion that's ultimately overdriven by a 0.68:1 gear ratio. A Dynotech Engineering Services steel driveshaft connects with the big-dog DTS Dana 60 axle that houses an Auburn differential and 3.73:1 gears.
Body
Priority was given to all the visible metal, so that the paint would be without flaw. With the bodywork addressed, it was then sprayed PPG Butternut Yellow (RPO Code Y), a take off on the original one that was offered from 1967-69.
Chassis
There is something to be said for a full-frame vehicle in that short of a complete rollcage to tie everything together, it is not a strict requirement for splendid handling characteristics or pull-your-eyes-out braking. Hotchkis applied their complete A-body suite: centerlink kit, tie-rod sleeves, tubular upper and lower control arms, 13/8-inch tubular antisway bar, 1-inch drop springs (512 lb/in), 1-inch drop spindles, adjustable upper links, tubular lower links, 1-inch drop springs (124/159 lb/in), 15/16-inch tubular antisway bar, and specific wheel damping in their Bilstein shocks. The return is a smooth, Caddy-like ride that becomes noticeably aggressive the instant it needs to be.
Rollers
Concessions to the braking system include Baer 13-inch rotors front and rear as monitored by four-piston calipers. Quality Bonspeed forged 18x8- and 18x9.5-inch modulars are paired with just the right complement of BFG g-Force KDW glue spools.
Chillin'
Stevens built his interior as a driver-oriented pod, complete with repro vinyl where needed, sublime Recaro seats, and Auto Meter instruments secured in a structure that Binkley built custom. The 40-year-old spaghetti was supplanted by Painless' finest loom and a Flaming River steering column was capped by a 13.8-inch-diameter WaterFall wheel.
