I would probably use it if gear ratio is not to high, your not going original (just body) why deprive yourself of progress,air cond,cruise control,plush interior, rack and pinion steering,
disc brakes, at least front, power asst'd.
fuel injection maybe,do you want to cruise? Or do
you want to race? Split the difference there's
plenty of room to have it your way.Take your time and take the road of least expences.Keep us posted. T

Your stock 60+ year old rear end will not stand up to the torque and hp of a V8. The first time you put your foot into it, and you know you will, you'll spill gears and axle grease all over the pavement.

A good 8" Ford or 10 bolt GM would be the best choice, if you're not going racing. If you are then the 9" Ford or 12 bolt GM are the way to go.

I think that I would seekout a chrys 8 3/4 setup. the best kept secret from ma mopar is that it is better than the ford (although not as popular) ratio's and carrier configuration selection from factory units is also better. just my thoughts on this

There is no way that old rear will handle what you have to dish out. Your SBC is putting out 4-5X the power of the original motor. I would look at a 8.2" or 8.875 GM, 8.8 Chrysler. Your car is fairly wide, so you should be able to find something that will work.
