    What's the difference in heavy truck motors vs light truck?

    I'm looking at possibly buying an 89 F600 , it has a 370 engine and is running off propane. I figure I can use it for my temporary needs and sell it when I'm done.

    I was just curious about the engine.

    Any help appreciated.

    The heavy truck engines usually have a place to mount an air compressor built in, they also have heavier flywheels to ensure more torque. In the past Ford made a 361, 391, 460, and a 548 (I thing thats the right last size), all industerial engines. Don't know about the others.

    Large truck engines usually have redundant V belts, larger alternators, more oil capacity, valve rotators, bigger radiators, heavier crankshafts, etc.

    They usually have a longer stroke as more cubes = more torque. It's the cheapest way to create low end torque.

    On the Dodges,gas,you see larger water passages,lower compression than the car models of engines.Some have different compositions on the crankshaft.

    For industrial engines Model designations will be 440-3,413-3,360-3.

    Standard engines will be 440-1,413-1,etc.

    PS,love those 'dash three' engines,nothing like a 440 that runs on regular.

    the easiest way to understand the difrence is look at the waranty given Cummins B (5.7 litres )series give 1/2 a million miles against mechanical defect , the L series 10 or 11 litres )gives 1 million against mechanical defect , the C series (8 litres ) caries a 350 000 mile waranty and its Crap ( Liner seals and sinking liners )

    This is a question Ive had too, and Ive been wrenching for 20 years. I thought the truck engines had a longer stroke, but I never knew for sure, and I never asked

    Well I test drove the truck today. As soon as it got warmed up good on the highway, she blew a head gasket :)

    I'm sure glad it didnt wait till I was driving it home. Be my luck it would have blow in the tunnel.
