I've always theorized that a minor problem MM had was the slower turning engines. Guys got into trouble with MM tractors breaking cranks and throwing rods because they would run them up to 2500 RPM's like an 806. MM should have recognized they were fighting a hopeless battle to get guys to break habits from other brands and re-engineered the 451 and 504 to run at 2250 engine RPM's. At the same time those engines could have been upgraded to spin-on filters and integrated turbocharging. White's cost to do this would have been minimal as the tooling was already there to make the jugs, head, and crankcase which would have needed minimal change. Make the new engine available company wide. They could have experimented for a bunch of years starting in 1964 to work out the bugs. We know that companies go out and buy a competitor's new release so White could have looked at the 806 and 4020 for engine ideas.
