Jim, There's nothing wrong with the A body 8 3/4 rearend. Should be a bolt-in( though I think you might have to change the driveshaft length), but they are almost bulletproof. If your going to be hitting it with the 273, I really don't see a problem there. That would be my first choice, and gears are readily available for them.
