I'm running the M4 on my bbc with the compressor delete and CS 144 alternator. Ill find my receipt but I think I shelled out $560 or so for the complete bracketry and pulley kit.

If you already have sbc brackets and pulleys then ya their conversion kit is the route to go. I enjoyed dealing with this gent.
