Gas engines will rev higher than diesels. 2 stroke gassers are capable of 12,000 rpms. The diesel in the cabover (4 stroke) only would rev out to 2,400 rpm and my C15 CAT (another 4 stroke) is only good for about 2,200. With diesels it is all about torque, not rpms. That and the heavier loads are why there are so many gears.
The old Detroit 318's and 238's are both 2 stroke diesels and they would rev about 3,000 rpms. They would also run 'backwards' if you gave them the chance.

True...but why would the engine max out at 1700?
