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.
