We've all owned and know of engines that just wouldn't wear out.
Old four cylinder Hondas and Toyotas as well as BMWs and Benzes, with both diesels and SI engines represented among the MBs, as well as the old iron MB V-8s.
The Ford 300 CID inline six, the Ford 3.0 Vulcan V-6, the various Ford 351 engines, as well as the typical SBCs. Let's not even mention the enormous and impotent Cadillac and Lincoln V-8s.
Any of these engines would shrug off years of use with little wear to show for it.
What did they all have in common?
They made no power relative to their displacements.
Is low specific output a major determinant of engine life?
