OK so one of my friends has a '74 camaro that he just droped in a 454 and he has the stock rear end and he wants to use the stock housing and use 12 bolt axle shafts and us 3.50 gears and a posi. I don't think it will work but then again i am a ford guy, but i have built some kick *** chevy racing engine.

You can get a 30 spline posi unit for you 10 bolt. This will allow you to use the 12 bolt axles. But you will have to shave the C clips about 1/16" The only thing I'm not sure about is the axle bearin dimensions, and if they are the same between 10 and 12 bolts.
Try giving Tom's Differentials a call.
Good luck.

Just tell him to get a set of alloy axles for the 10 bolt and be done with it. If the 10 bolt blows, get a 12 bolt. The 9" Ford can handle a little more torque than the 12 bolt GM, but because of the lower location of the pinion has more drag and sops up more power. If you really want to get strong, go to a salvage yard an pick up an axle from a 3/4 ton GM pick up truck. They come with huge gears, semi floating axles that can be removed with the wheels on, and big gear ratios.
