44,44S and 45 are pretty much smallblock Chevy plugs. The 46N is for 62-70? 6cyl Chevys.

Some of those might be of great interest to muscle car purists, especially old Corvette guys who are often extreme on original parts.

Billy's right on the money, above. The 302 Z28s specified 43 heat range, but it almost always proved to be too cold, so many Z28 owners migrated to 44 (for occasional WOT blasts) or even 45 plugs (for low-speed idling/cruising). Same story for Corvettes with engines like 327/365. Somebody will want them.

Thanx guys!

I appreciate the help! I have very limited GM knowledge.

I'll try and check with the Camaro and Vette crowd forums
