Engine and Transmission
The original engine was a 350 tuned port with fuel injection and the automatic transmission was a 700R4. In 1985, GM introduced its Tuned Port Injection (TPI) manifold on the Corvette and the Camaro line. The TPI system includes a manifold base, two sets of runners, a plenum, and a throttle-body. The TPI manifold was originally designed for 305ci engines with 19 lb/hr fuel injectors operating at 36 psi, and employs a long and narrow runner to enhance bottom and midrange torque. The 350ci TPI-equipped engines use the same intake as the 305ci with larger 22 lb/hr injectors at 43.5 psi. The additional cubic inches broadened the power curve, but the long-runner intake limited rpm. The LT1 engine replaced the TPI in the Corvette in 1992, and in the Camaro in 1993.
LS1 engine out of a 99 Camaro donor that had been wrecked. The LS1 engine and 4L60E transmission had about 8000 original miles on them at the time of the swap. The LS1 was used in the Corvette from 97-04. It was also used in 98-02 GM F-Body (Camaro & Trans Am) cars with a rating of 305–325+ HP, which was rumored to be conservative. The Generation III 5.7 L shares little other than similar displacement, external dimensions, and rod bearings, with its predecessor (LT1). It is an all-aluminum 5,665 cc (5.665 L; 345.7 cu in) pushrod engine with a bore of 3.898 in (99.0 mm) and a stroke of 3.62 in (92 mm).
LS1 Engine with LS6 Upgrades. Many mods and upgradse inside and out. Dyno tuned right at 425 HP. I designed the hood liner and had it made by Quite Ride Solutions. Cold Air System was made by Spectre R&D Department.
