GM never made a 450 tranny, you probably mean a turbo 400 tranny and yes it can be done.
No, they will not.

yes.
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. My #573-692-3558 The motor has 20,000 miles on a complete rebuild. Water pump, alternator, carburetor, distributor all new with the rebuild!
