Just to add to what Matt said,
The m-18 is the last and best of that flat head series motor
It has increased and thicker webbing throughout the block.
The flywheel taper is increased in diameter.
It uses Mahle FORGED pistons of robust design.
There were also running improvements in its design, like a 30* valve angle.
Thus the “Magnum” term really meant better/improved.
If it weren’t for emission requirements and fuel improvements I’m sure it would still be in production.
