I have a '51 chevy im working on, its a 3/4 ton with the inline 6 and 4 speed with granny gear transmission. My initial plans were to put the body onto a '78 cheyenne frame since I found one at a really good price that already had a 12 bolt in it and disk brakes and was set up for a sbc/tranny combo. Now im wandering if there is any way to mate the TH400 I have to the inline 6 thats currently in the truck. The truck is all original and runs in its current condition I just hate straight drives and want to switch to an automatic. Does anyone know of an adapter out there to make this combo happen?? Thanks for any help.
