Should i do it or not?

Not giving up. Just dont have alot of time. I have 2 VW projects that i need to get done first. ^5 karmann ghia, and a 71 stupidbeetle for my son. After that the merkur then the spitfire. the spitfire is going to be a one off frame and alot of custom fabrication. It looks like the v8 will fit pretty nice in the merkur. Im thinking of selling my 904 parts and either going auto od or maybe picking up a 5spd tremec or something. does anyone know if there is a factorry bell housing that will allow a ford T-5 or tremec 5spd to bolt upto a SBM?
Thanks
