The swap isn't a direct swap. At the least you'll need to move the frame mounts. These cars came with multiple engine options throughout the years. So a lot of engines will bolt in without too much trouble. For sure the Chevy 350, the Olds 350, and since the Grand Prix came with a 301 Pontiac at one point, the Pontiac 350 should also fit. You'll just need to figure out where to move the frame mounts and get the correct engine mount. Depending on the engine chosen you may need to change transmissions also.

I put a 1972 350 old's engine in my 1984 cutlass supreme. It had a 307 and the swap went smooth. It bolted rite up to the turbo 350 transmission also. The engines have the same block so the weight difference was no problem. My cutlass is for sale if you know anyone that is interested.
