lOOk at my rear!

7 1/4. They're not too bad for normal driving. Not even that bad for burnouts. They become a problem when the burnout stops and you suddenly catch tracion. Kiss those spider gears goodbye! It just happened to me.

The good side is, if you can consider it good, is that A: they're stupid cheap to fix and B: you'll get LOTS of practice replacing the rear end.

Charlie_S is a kickass slant 6 racer and he let me in on a little secret. I'm probably gonna get beat up for even suggesting this, but a Ford 8inch rear is a lot stronger and will bolt right up with no mods other than afro-engineering a hybrid U-joint. They're readily available and CHEAP because the disg-ustang crowd throws them out in favor of the 9inch (like we scrap anything in favor of an 8 3/4) and many come with posi. Luckily I scored a SG 8 1/4 for free so I didn't have to sell my soul to the Ford devil.
