"I am running a 1990 Corvette Speed Density TPI setup on my 1967 Camaro.
When it is finished I will post pictures. I was going to use a taller cam, but I ran it on Desktop Dyno, and in the RPM range I will be running for a mostly street motor this did show to be the best.
The build is in the beginning stages, and the Manifold is not back from being converted from a stock LT1 to a first gen configuration, but it seems to be going smooth. The reason I went with the LT1 manifold conversion over a modified TPI is that the runners are almost 13 inches shorter. I would think this would flow much like a single plane manifold, and perform in a higher range than a standard TPI. This should prevent the engine from dieing at 5500 RPM. With the 30lb injectors the setup should easily push over 400hp, and well over 450ft lb torque.

? The engine is a mild 383 (6.27 liter) (5.7 liter-350 cu in block, with 4.030 bore and 3.750 in stroke)
? Using a TPI harness, without the EGR, or VATS.
? It uses VSS, and 3 wire O2 sensors.
? The Engine has 10.25-1 compression Speed Pro pistons H860cp-30 flat tops.
