I have a mostly stock '65 425 10.5:1 comp. I have a performer intake, dual exhaust manifolds, and I am running an Accel coil and pertronix ignition. I am currently running AC Delco original type spark plugs, I am wondering if there is a better plug out there that I can use?


Thanks

As long as your plugs are gapped properly you should be fine.
