    Looking for a Rear End that can Handle up to 600hp

    I've got a shitty 10bolt under my car with 3.23's its fun and all but the moment I slap any sticky tires on it and launch it hard I know I'll blow the rear end out. Any reasonably priced ones out there? And how hard is it to convert a 9" over to a third gen F-body?

    I really wish I would of kept my 9bolt rear end out of my firebird and put a 10bolt in it when I sold it. Probably could of got some decent money for it or kept it for myself just incase :P

    Preferably looking for a Ford 9" or a GM 12 bolt. The 12 Bolt would be easier to work with. I just can't seem to find any used ones around than can get freshened up and thrown in.

    Don't even waste your time converting it to a 9" unless you're going to be converting gear ratios all the time for road racing. The 12 bolt conversion is much easier and less expensive.
