I'm looking for a 8.25" rear to switch out the 7.25" 9 bolt rear, I want to keep the car "numbers matching" and of beef up the 273 that the car came with. I'm not expecting to get ridicules hp out a 273 but I can get closer to the 280 hp by swapping out the intake to accommodate a 4bbl carb. would it make sense to swap the rear or would the 7.25" hold up?
