I don't want to spin the rear-end out of it, but I've had it perform with the 283 quite well (smoked the tires from a down shift 3 to 2 at 40ish mph back when it had a manual)

LOL ... yeah, no replacement for displacement.

Thanks

From what I have been told the best thing to do is put a 9" ford in and it will look close enough to the factory with the 3rd member. I personally don't want to put a ford rear end in my car and am looking for a Pontiac Olds 9.3" rear end from the same years as it should be a direct bolt in and they can handle a lot more power.
