Thanks guys! It's been a while since I've been here but I'm back!! To answer a couple questions, the GEN III engines all run separate coil ignition fired by the PCM. It's very accurrate and puts out a NICE spark. I'm using the factory type of computer that GM Performance has which actually has been set up for street rods by Howell Engineering. I'm using alot of LS-6 parts like the intake, camshaft and valve train. It should put out an honest 400 horsepower. I have a 383 on the engine stand that I could have used but I really like the way these new ones run. Ill post a few more pictures later. I just got the doors back on it after installing the hidden hinges and bearclaw latches.
