spark plug heat range????
what heat range plug would work best for this application?
383, 10.5 to 1 compression, iron heads, MSD ignition, 292/500 lift
camshaft and a holley 770 avenger carb. I am currently using the ACELL shorty plugs the heat range is not specified on theese. my heads are the old camell humps so they use the big spark plug base.
thanks

Ooopps! Those were all late style small (peanut) 5/8" plugs.
Never mind.
