Exhibit A: The 396 cubic-inch small-block in our 1988 Firebird project car, which was built by Strope Speed Shop. This naturally-aspirated 11:1 mill packs a stock, clearanced, .030-over block, splayed billet main caps, Cola forged crank, Lunati Pro Mod rods, Lunati custom forged pistons, CNC-ported AFR 190 aluminum heads, a Comp Cams hydraulic roller cam, Comp Cams valvetrain, ACCEL SuperRam intake, and SLP ceramic-coated 1 3/4-inch shorty headers. On an engine dyno with a Holley 750-cfm carb and 300-36 intake, this mild "smogger" 396 made 481 hp at 5800 rpm and 485 lb.-ft. at 4200 rpm. In fuel-injected trim using the stock ECM it made just 226 rear wheel hp--around 290 flywheel hp. Something--or a combination of things--was very wrong. As we would eventually discover, the factory computer and the restrictive factory air ducting were the culprits.
