What trans are you running now? It is easier to swap everything into A body housings. Just use a 307 front bearing main housing and a 30 spline output housing. The Bell housing is not a problem, I had a 71 340 bell housing and trans in my 64 Barracuda. Have to agree with Toolmanmaike, unless you are making over 500 ft lb of torque, sell the Hemi Box and get a good A Body 833. Brewers Performance has all the stuff to hook up a later bell housing to an Early A.
