It is not a fuel problem. Fuel pressure is 6.25 psi and constant. When I said falling on its face, I mean it starts breaking up to the point where it sounds like your going to lose some parts and is losing power like it is dropping cylinders. Since it is just under 12-1 compression and I am running 110 vp fuel, I know it is not detonation. The reason for using the autolite racing plugs is because they are short and do not have a projected tip. I have 2 plug wires that touch the headers even with these short plugs. I have those two wires wrapped with protective heat shields so they dont melt the boots. The other reason is that with the projected tip plugs, the pistons have a tendency to close the gap on them. I am going to try a hotter plug and new wires and coil to see if that fixes the problem.
