I'm putting a motor together and was wondering about spark plug recommendations, cause I can't seem to find any. If you need to know anything about the motor just ask.

Thanks.

Forced induction or N/A?

Regardless, I'd have to lean towards the NGK's. Which heat range would depend on your mods, or future plans.

I'm N/A and my motor is as follows. Trick Flow Track Heat heads, Lunati Cam 232/242 dur@.50 with 574/595 lift, Victor Jr. high rise intake, proform 650 race series carb, speed pro hyperutectic pistons, trick flow 1.7 roller rockers, custom length pushrods. I could use a heat rating explanation too.

Thanks.

A colder plug is going to allow you to run more timing while helping to avoid detonation. And being N/A, "lean is mean"...to a point of course. This should explain better...
