You might also consider the 200 or 700 OD transmissions and still change to a 3.42 or 3.55. You will still get a good first and with the OD retain a good highway gear. With a 64 block you don't have the adaptor and starter problems. Get a BOP flanged 200 and it may be a lot easier. Either 400 200 or 700 will have some floor interference problems but those are solvable.

I had to add a metal plate to the crossmember for the relocated 200 mount and hit the floor in 2 spots to clearance the 200. not noticeable inside the car under the carpet. 3.90 rear. A little much but less rpm than 3rd in a slim jim with 3.08s
