I've got an M123A1C and it has been an awesome truck for my logging business. Unfortunately, the motor just went on me. It broke the crank and now I am having a heck of a time finding replacement parts. At this point, I'm in such a need for it and having such a time finding a replacement V8 300 or parts for it, that I am thinking of just finding a motor to fit it. Any one have a suggestion of something that will do the job? The 300 Cummins was 785 CI, 300hp 300RPM to a Mack TRD XT72 trans., 5spd with a hi and low. I just need something that will fit and bolt up.

I have an M123A1C with a V8-300 Cummins. It is a '68, so it was when Mack went back to producing them, after CONDEC had taken over that line for a little while.
