The 454 even uses the same distributor as the small block, so caps and stuff are the same.
I used a Th400 behind my 454 swap in my truck. It takes an electrical kickdown rather than a cable like normal trans use. I bought the Lokar kit and am very happy with it. A good tranny shop can easily build a 700R4 that will live behind that engine, but it will cost you some more money than a Th400 build will.

SB & BB dists. will interchange. Kickdown is electric-works off switch mounted on gas feed bracket-you should already have it-one wire to power switch on-one wire to connection on trans (driver side). The switch can still be purchased from GM. Turbo 400 will need an adapter between trans and tranfer(so will 700)
