Hey guys im wondering what everyone thinks would be the best plug for my car. Heres what im running.....30 over 440,10:1,292 purple shaft,750 DP,Eddy heads,TTi headers, Brand new Firecore(ditributor,wires,coil) and an Msd 6AL box, auto with a 4:30 gear. I have been running Autolite 3924's. For my combo what do you guys think i should run and what should i gap them at? I was having all kinds of problems last year so i changed the whole ignition but i only got to drive the car once. So i have no idea if ive fixed the problem or not. I think the plugs were shot before i changed the ignition. Anyone point me in the right direction?..Thanks..Joe
