[ZMAN1969]

Well I cant say anything about the A/M boxes but really how specially tuned can they be? the OE specified different boxes to feel different -act faster on the performance cars so when saginaw builds different ones arent they specially tuned? not trying to argue here. I'm basically a cheap bastard and would just as easily pickup a boneyard box -IMO if the box isnt leaking its probably good as its not much of a wear item, but you do get what you pay for too. I'm actually looking for a third gen IROC or WS6 box for a chevelle of mine. good luck with your project just thought I'd post up a low buck option
