What plugs?? Vortech blown 338SBC with AFR heads

[fletcherscustoms]

My 70 had a fit the other night and fowled out some plugs. I cannot cross reference the existing Bosch plugs to anything available. Bosch claims they don't even make them. Can anyone give me a reccomendation for a set of plugs for a 388SBC with a vortech blower at 10 psi, with AFR 220 angle heads

I've had very good luck with simple Champion copper plugs on my Vortech-blown 383, the RC9YC. Running around 12# of boost.

AFR calls for an Autolite 3910 starting point. You will want to go a couple of heat ranges cooler since you are boosted and start there.
