I'd say the 292 was somewhere between an ordinary pickup truck engine like a generic 350 and a true industrial engine. Comparing it to the Ford 300 is a pretty fair comparison- they're both a cut above just taking a car engine out of a 4-door sedan and putting it in a truck. They also compare more or less to the "-2" Chrysler industrial engines, whereas the big GM sixes were built more like the "-3" Chrysler industrial engines. Examples of Ford's true industrial engines similar to the GM 305 v6 family would be the 370 v8 and the industrial version of the 429. Chrysler had true industrial versions of their 50's Hemis (354 and 392), then later the slant-6, 318, and several versions of the 361 and 413 v8s, differentiated by "dash" numbers. The 361-2 and 413-2, for example, had a few industrial goodies like sodium-filled valves, full roller timing chain, etc. The -3 versions had all that plus completely different heads with lower compression, different coolant flow (a water manifold at the back of the head tapped hot water off both ends of the head), more coolant passages around the spark plugs, coolant-heated intake manifold, HUGE water pump that stuck up 4" above the intake, etc. Lots of people don't realize that even though the 413 and 361 were discontinued from cars in 1967, they were built as industrial engines all the way through 1975. The Ford 370 and 429 made it well into the 80s if not the early 90s.
Of course all that is pretty much gone by the way now since diesels have displaced gas engines from most industrial/heavy truck applications.
