I had heard Paccar had built a new big truck engine for the air police.
Unfortunatly it is a DAF , built like a car engine.
The Camshaft is belt driven , and its failure may cause engine death , as so many cars do.
Not much chance on a marinization* as a boat engine with this failure profile , but for the gear heads ,
