Here's the setup, 350 bored 30 over, stock crank, flat top pistons, GM vortech heads, making 10.5:1 CR, edel airgap rpm intake, 750 edel carb, headers, long duration cam, holley red electric pump, mallory FP reg. Accel HEI supercoil, moroso 8mm wires, ac R44TX plugs.
Problem is the plugs are consistantly fouling. Can't clean them and reuse either. I was wondering if there was a plug more resistant to fouling, but the same length or shorter than the R44TX out there for Vortech heads? due to the headers, there isn't anymore room for longer plugs than these. if you need anymore info to help figure this out. lemme know. Thanks.
