Spark Plug suggestion.

[71Runner]

A search here yielded nothing, so I thought I'd post. I'm going to be changing plugs soon and was wondering what you guys are using. My engine is a '71 383. Heads are cut a bit to yield about 10:1 comp. 284*/.484 Purple Shaft cam. Dual plane intake, Holly 750 DP,Hooker Super Comps, 3k stall speed converter w/4:10 axle rear. Car usually driven a mixture of around town cruising with some highway use. What would you guys suggest. I don't recall whats in the car now, but probably Autolites. Thanks.

I've used autolites, but normally i just get champions.....hoping to try out the accel shorty plugs when it gets time to change, though lots of guys use NGK

Thanks Landon, what plug numbers would I be looking for as far as heat range goes?

I use Accel 134, works good with a double pumper.
