The holes are already drilled in the frame for the motor mounts, there are a bunch of holes, you just have to figure out which ones to use for Pontiac motor mounts. The transmission crossmember is unadjustable, you might be better off using a Turbo 350. The biggest factory radiator they make is a 3 core, the radiator from a 3rd generation F body will also fit. Dual exhaust is also another problem, they make aftermarket exhaust systems but they don't fit very well. To do it right you need to remove a section of the crossmember right out. You can weld a brace on top with some channel iron and use a cutoff wheel and remove a section of the crossmember and run the exhaust right through the middle of the crossmember.
