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.
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.
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.
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.
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.
