I have a 48 3600 with a 292, T5 with .86 OD, and a 4.11 14 bolt rear end. When I swapped the rear end, I should have found a 3.73, or searched for a .72 OD transmission. Otherwise, I really enjoy it. You will have to modify engine mounts, and the fan does sit too low with respect to the radiator. I am still working on my final cooling solution. I am trying to stay away from electric fans.
