My neighbor has a 74 Mustang with a V6 that is seized up. I know a V8 conversion won't be that difficult, but I would like to know some specifics about whats compatible with the V8 from the V6. Does the bell housing interchange? I'm guessing no. It's an auto trans, will it need a new torq converter? I'm sure motor mounts will have to be changed. Anything else you can help me with would be greatly appreciated.
