Hi All,
I'm a brand new member but I've been researching a swap on this site for years. I've been keeping an eye out and finally found a 4BT engine that I bought sight-unseen, without any time for research. I got it for basically scrap value and the more I dig into it, the more I feel I may have won the 4BT lottery. It's an industrial engine, which I realize is sometimes a red flag; but it was the powerplant in a giant mobile gantry crane, controlled with a throttle, which I think may have led them to produce it to basically a road-spec. It has less than 2,000 hours on it and was serviced regularly. I've started the engine and it runs and sounds great. After i got it home I checked into the actual part numbers and got info from Quickserve and I've got the following information out if it-
ESN46201894 CPL# 1963. Build date is April 2002, it's got a P3000 pump (looks like the P7000 pump but is industrial and less common) but is rated at 130 hp and has the RQV road governor. Turbo is the HX30W and it has the water jacket aftercooler with the air intake heater which also seems to be uncommon. Oil pan is rear sump.
My plan is to put it into my 1946 Chevy 3/4 ton which can handle the engine weight, as well as the tall engine bay to accommodate the aftercooler and the up-turned turbo. It also has a very beefy 1 ton rear diff. I also picked up an NV5600 6-speed (way bigger than I need, I know, but 6 speeds are cool and the NV4500 is basically a myth in these parts) from an '02 2WD Dodge 24v complete with engine adapter, flywheel, starter, clutch, and driveshaft.
My problem is I'm usually a huge skeptic but the only potential downside I see so far is potential steering box interference with the driver's side starter on the NV transmission, and the turbo exhausts to the front so it'll need some fancy routing or a different / flipped manifold. I'm waiting for the other shoe to drop... what am I missing? Did I really luck out on this engine?
Here's some pictures, thanks in advance for your advice....

Looks like you have a good plan.

Years ago we found a formula for converting equipment hours into miles. It based on the computerized Dodge speedometers that gave both hours and miles traveled. It is (Highway Miles=Hours x 45) So 2000 hours x 45 comes out to 90,000 highway miles. 4BT's on average have a history of developing coolant head gasket leaks around 130,000 miles. Looks like you will some time left before that develops.

GM made their rear axles "beefy" due to the unavailability of not yet having the modern alloys we have today. The weak links of that rear axle were axles that break and in some cases pinion bearing and/or pinion bearing seals. You may want to keep an eye out for a newer replacement from at least the 1970's or newer that has the same width and possibly the same bolt pattern.

I believe you can tilt the engine from vertical for clearance as they did in the step van retrofits. You can also offset the engine from the center of the chassis. You just need to maintain the drive line requirements for angles and lubrication of the transmission.

I'd say you did very well in the engine lottery. Those engines with the P3000 aren't all that common but one shows up every now and then. Although it doesn't have quite the power potential of the P7100, several of the mods can be used on that injection pump. Two common mods would be the 3000 RPM governor springs and a #10 torque plate. You can also adjust the timing advance a bit. The vertical exhaust on the turbo can be worked out. That outlet elbow can be unbolted from the support bracket and rotated to a different position. That bracket was there to keep the weight of the muffler assembly off the turbine housing. If you want to reverse the turbo with the exhaust facing rear that can be done. You'd have to change the exhaust manifold to 3901635. May also need a spacer between it and the turbo because your engine has a very rare option on it. It has the intake heater for the aftercooler. Yours is the only one I've ever seen and it's 12V. My industrial catalog shows a 24V model but yours is a different part number. Being in Canada that may be big plus for starting in cold weather. Unless you plan on manual steering on the old Chevy you'll need a power steering pump assembly for the P pump. Member Nascar Mark can help you with that. He lives in Canada. On the transmission hook up, there may be another option but of course you already have the parts for the Dodge setup. Quick Draw Brands may have an SAE3 bellhousing for that transmission so you could use the existing one on the engine. They have one for the NV4500 but not sure it would fit the NV5600.
