C609T Posted November 12, 2020 Share Posted November 12, 2020 Does anyone have the break down for engine codes ? For example R685, R686, R795. I thought it was listed on here but I can’t get it.

doubleclutchinweasel Posted November 20, 2020 Share Posted November 20, 2020 (edited) Here is yet another partial list. I pulled these numbers off of some PDFs I have of old Mack brochures. I only listed the ones I can read with some degree of certainty. I have others, but can't read them well enough to trust my eyes. So, this is by no means complete. But, it gives some idea of the variety of engines they used over the years. Incidentally, my 1970 R-611ST had the ENDT-673C, which was rated at 250 HP @ 2,100 and 701 ft-lbs @ 1,600.
