No sixstarved, you aint goin' off, and it aint got nothin' to do with who's right/wrong.

(Heck! I don't know, and if I had to guess, I'd say that the first generation Camaros/Firebirds share those same components. I'd make that best guess because all auto makers are cheap. It coste money to retool--the reason why we have coperate GM engines rather than ones by seperate divisions--so why would they they retool on sister cars?)

I'm not even going to try to guess on Camaro/Firebird interchange, but on the 7 through 9 brids, I cannot see the reason that they wouldn't interchange.

If there is an interchange problem, it's to everyone's advangage to know about the problems. (I'v never done any six cylinder cars, so I didn't know there was a difference. I though that was a MoPar trick. For instance, you cannot just chunk an 8 into a 6 cylinder Duster because there is a torstion bar or cradle issue.)

So the only way to address interchange problems is to speak up.
