67 W200 Which motor would you use?

My original plan was to build a street rod but now I think I will keep it original. The 383 needs to be gone thru. It smokes bad. It hasn't been started since 2003. New battery and a little juice down the carb and it fired right up. Does anyone know of a disc brake conversion for the front? Would the brakes out a 80's or 90's truck work?
