Based on a comment by John S on another post, I am curious what is the difference between the 354 Turbo and 372 engines other than cubic displacement. The reason for asking is that I have the 372 engine and I could put it into my 1955 chassis or use it to replace a weak 310 in another 1855. This 1855 is our loader tractor and usually does not get a lot of hard work with a loader on the front and a forklift on the back. Is the 372 engine more geared to the lessor hp needed for my loader tractor or will it perform like a workhorse for the heavier 1955. It is a combine engine and most of these have to run full throttle all the time. I already have the tub etc in a junk 1850 along with a spare early 354 Oliver engine for parts. Do I hold off and power the 1955 chassis with a cummins?
