Just did a motor swap to edelborock aluminum heads, a B-303 cam, Pete jackson "noisy" timing gears, GT-40 intake, 65mm throttle body, 24lb injectors with a 73mm c&l mass air meter. Also the short block is out of a 95 Gt with 80,000 on it. I have good fuel pressure and good compression but it runs like a pig! It sounds really good but no go! Also the motor kind of jumps an awful lot, The motor mounts are brand new and timing is set at 14, I also used the flywheel off the new motor, had it machined and am using a new king cobra clutch. The car also has a bad vibration starting at 4,000 rpm. sorry for having to tell you my life story but I need help my stock motor with an E cam would spank this thing. Hope someone can help Thanks
