Ok I have bought a new to me but a used motor that has been rebuilt. It is a 302 with a e-cam,gt40p heads, Trick flow street heat intake, 24lbs inj., 24lb 73mm mass air,70mm throttle body, mac long tubes, new cap and rotory button. Ok so here is the problem we are having problems with the timing. It wants to sputter and kick and jerk alittle when driving. Idle is at about 850 rpms. Ok also another question. I have the gt40p heads on the motor. Is there any kind of special spark plug or spark wires that I need to get? And also what does the timing need to be set at?
Thanks for the help I really do appreciate it.
