Plug heat range\gap reccomendations
I think you guys will help me more than the guys in the small block forum (guess they get this question alot) so here it goes.
Ive got a 302 in my truck with a 500 CFM Holley, pretronix, accel superstock coil, and quality rotor, wires, and cap. The factory reccomendation for the plugs is Autolite 45's at .35 gap. I have the timing set to about 11* base. I would like to know if I could/should run a different heat range. I have Autolite Platinum 45's gapped at .60 (runs fine, BTW- regapped because I *heard* that i could squeeze some MPG out of it), and I usually run 87 octane.
