Actually, I really have been thinking I need a complete drop in NHC250 engine after all the trouble I had finding parts for my old one.
Assuming the 400 and 8.3 are otherwise equal as a replacement, you might also consider the availability and price of repair parts.
Ok, I thought you were talking about a 800 series. Disregard what I said earlier (except about the 250 and 400 having the same RPM).Thanks for the thoughts. It is going in a M925 that already has the MT654CR Allison.
Either one (8.3 or 400) should bolt in. The 8.3 I have is currently sitting in an M931 truck so I know there are no clearance issues.
Woo-hoo, air lockers! Nice! What is your intended application for the truck. I think the gear change might be very desirable, unless you will have a higher gross weight and/or operating off road.Keep in mind that if you put in an NTC 400 and use the power for really fast acceleration as opposed to more gentle acceleration and maintaining highway speed you'll be twisting parts off the drivline in short order.
The injectors and turbo in the 400 will have a big effect on how the engine is going behave and what economy you'll get. there's a world of info on Cummins 855 engines at Pittsburgh Power's website on selection.

Sounds like a cool project. The stock 250 might meet your needs as-is. If you are planning to tow/haul big stuff, I would go for 400 hp.M1075,
I am purpose building a go-to recovery truck. I don't have anything but bobber deuces and I need a heavy tow rig to drag other treasures home. You of all people know how nasty Hooks can get!
The mid-axle power divider, air shift front axle and 5.81 gears will be a treat for on-road travels. The air lockers and hydro winch will cover the dirt. I am watching Adam's post about 5 ton locking hubs. These will complete the package.
On Road: power only to middle axle, front axle completely disabled.
Off Road: Power to all 3 axles with all 6 tires pulling.
