I installed the NGK racing plugs in my car, they were the cross referance to the reccomended auto lits for the Dart heads and i gapped them at .035. I thought it sounded good with the 11:1 ratio. Runs great and i have the MSD so i just figgured i would see what everyone else thought. Just took the intake off today to epoxy a runner that had a small crack in it and it should be fine now.

Yeah, .035" to .038" is where I run the TR6.

Sweet, i just remember reading some **** a while back and i figgured it was where it would like to be. Wonder what plug i should run for N2O? Even the gap.

I was running an AFR 210 head with a 250 shot and I gapped mine to .032, it was an autolite race plug I think it was 2492 or something like that, you could go one stage warmer the 93's For nitrous I would gap them between .032 - .036 depending on how much you spray.

I always pulled a little extra timing, but don't pull too much timing, that's when you'll get carb back fires and that'll blow **** off the top of the motor

Yea, i do back timing off, but i usually NEVER gapped plugs for spray, i have actually never even installed lower heat range plugs but then again, those old motors were 9.0 to 1 at most and just stockers.
