Although you do not mention the type or year of the car, my guess is it is a 7.5. A 455 will make short work of that rear unless you drive it like a granny:laugh:
7.5 rears are great to roll the car around the shop on They call the 7.5 the "glass 10 bolt" for a reason.
its a 80 cutlass salon, 3.8l buick, 3 speed manual, 2dr, black in and out i thought it would be junk, i was thionking 9" .....i have a 9" but its in a 81 pickup......, i was told i couldnt shorten it, so i guess its useless
