Re: spark plug selection?
I made the mistake in using Bosche Platinum Plus, didn't fair so well in the %.0. Buddy of mine used them in a Firebird with a 301, had the same problems I had. I switched to Autolite XP's, haven't had a problem so far, but I've only got a couple of hundred miles on them. Local tracks seem to love them, though.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
