I'm a little confused on the whole bellhousing thing. The car is a '53 but I have two engines for it. The one that is in it now is a 235 out of a '59 and the other one is a 235 out of a '60. I'm planning on rebuilding the '60 with some performace goodies and then swapping the engine, tranny, rearend, etc. So, with that said, what concerns would I have with the bellhousing, etc?
