What spark plug gap is the best for the high and mighty 4.3L v-6 using the ac delco spark plugs...or better yet what are the best spark plugs to use and what gap for them?

Thanks,
Joshua

 

can anyone offer me some advice?

check the owners manual.

 

Come on man, give me a little credit. Owners manual says .055 but I was wondering if anyone was running anything different and if so, what were they running and what gap. There are a lot of people that do not run what owner's manual specifies. Uhh...thanks for your help anyway.

Run AC Delco plugs and stock gap. Unless your have a blower, turbo, or nitrous moving the gap will not help much may even hurt things.
