Spark Plugs
I have an 88 TPI 350 IROC and I was wondering if we can use the longer threaded spark plugs? Im looking into buying some NGK's but it seems to have more threads on it than the AC Delco's. Ive read the thread on the spark plugs and im convinced that NGK would be a good choice.

Re: Spark Plugs
NGK does make stock replacement plugs that should match the ac delco versions. May just want to doublecheck the cross reference on the plugs you're finding.
