The back of the BLOCK on the MV's and on the 6.9/7.3's is the same. There
are two different flywheel housing adapters which will fit either one. One
of these goes to an SAE #2 or #3 (?? not sure which) bell flange, the OTHER
goes to a big block Ford bell-housing bolt pattern.

All you need to do to figure out where the power went on the MV's is to
take a look at the heads !! The valves and ports are about the size of
those on an SV 266 !! These heads were a typical early '70's 2/3 strangled
emissions oriented design.
