Just so you know, the Cummins M11 engine weighs in at 2200 Ibs . I worked on these engines at the transit agency here in the Seattle area. Good engines but they are computer controlled and have had problems with the valve train and injectors. Also be very careful about the fuel you use and replacing fuel filters. Never prefill the filter. Always let the fuel pump fill it. The filters are a 2 micron filter. The injection pump is very picky about any small foreign object !

That is a great tidbit of info. Ive had a few trucks with M11 Celect at various hp levels and a buddy of mine has a crane outfit with a couple of kenworths with the same power.

Thanks!

Well the plot thickens ....
I was not planning on going in this direction but I happened to find a verywell prices 1996 Western Star with a Cummins M11-280E Plus and a 10 speed with overdrive.
This engine is way bigger than what I originally planned on, but at the price I could not refuse. Worst case, I can always sell it for parts if it doesn't work out.
I was told the engine ran, and I believe the guy. The truck was retired because of frame damage. It looks complete and in decent condition, but it's missing the alternator and the compute controller is disconnected and unmounted for some reason. I'm not familiar with these engines since most of my experience has been with smaller ones like the Cummins 5.9 and Toyota 12HT, 13BT, and 3B. So I don't yet know what I'm getting into ...but it might be interesting ...
The 10 speed transmission has an overdrive gear of 0.73, but since most of the M11 engines are rev limited to 2100RPM and work ideally in the 1500-1700RPM range, this will be painfully slow. Which is fine for now and most of the work on the property.
If I find myself wanting to take this on the highway, I might invest in getting custom gears made for the transfer case to change the final ratio.

Sounds like a job for a 13over..cheaper than new gears.
