I'm running a chevy 350 on methanol. The motor has the double hump heads. All last year we ran the Autolite 303 plugs with no problem, but this year we changed the intake and cam and the motor seems to be getting more fuel. Now, I'm having a problem with the plugs fouling out. I was wondering if maybe the plugs are too cold. Would a hotter plug help, or maybe a colder one? If so, what plugs would you suggest?
