Engine swap questions
Hi there, it's been a while. I am looking at swapping out a 351 Cleveland ( 1974 era ) with a 351m/400 engine ( 1976 era ). Besides the new electronic ignition/electrical I am looking for feedback regarding the transmission mating and possibly an issue with motor mounts. On another subject, same motors, can I pull the 4V carb and manifold from the old and install them onto the new which currently has a 2 barrel carb ? Your thoughts and opinions are appreciated.

Thanks for the info, the 351 C that I currently have appears to have spun a crank bearing ( I think without pulling it apart yet ) The other engine, 351 M has already been rebuilt and is in good running order, minus the benefits of the 4 barrel carb.

What car does the 351M come from? You may need to change engine mounts also.
