Posting the picture of the original power plant. NTC 400. (855) We may do something with it later, but the truck assembly is priority one.

We are using the steel top pistons used in the celect plus engines, good cam, custom injectors, and fuel pump calibration. Shooting for 550. The engine originally was a 400 with tri tech aluminium pistons. We are still debating on turbo, but most likely an HT4C. We're also ditching the original 14" clutch for a real one haha.

The truck is a farm truck and hauls hay and tractors. Lots more hay than tractors.
It is awesome to work on something that does require an ECM.
You would be surprised at how much power can be made with not that much of an increase in injector flow, the factory 605hp generator set uses about the same fuel flow as the old 475hp TT engines.

If you aren't using diesel controls then I might suggest Premco out of texas for fuel parts, they manufacture everything in house, this is my go to now for injectors, and they do anything from bone stock to wild.

I bet I wouldn't be surprised. With just a tiny increase, you'll net large gains in energy produced. That's how you build a really good running diesel using conservative fuel pressure numbers that doesn't eat camshafts and upper rod bearings.
You start dumping massive amounts of fuel out of fire hose nozzles, and you're only creating an opposing force in combustion.

It's in there. Still some fabricating ahead to add the charge air cooler and plumbing. Hope to have it running by weeks end.
I really dig the antique dash.
