I have a '57 M45 gasser (I think it's the oa-331) that needs a new motor, thanks to me. Since I need a new motor, I thought it would be a good time for me to go diesel, and then I thought, why not go big diesel, and run singles on it. I want to put a 250 cummins in it and run the 14.00's on it, but I also saw a deuce that has 16.00's with a lift on it and extended tandem axle (hotroddeuce). Will I have a problem with the 250, what tranny would be best, should I re-gear, will I need to run longer lines, etc...etc...any advice will be mucho appreciated.

Have cubic dollars on hand.. You are trying to squeeze 50# of feed in a 5# sack. There are better choices.

If you are pulling out the OA331, PM me what you would take for the distributor assembly. One of our members in Spain is looking for one.

If I had a gasser M44 series truck, it's be a 465 multifuel so fast your head would spin. It fits right, you'll be able to diagnose, troubleshoot and order parts directly from the TM's, it's value will increase and parts are cheap.
It's either that or a 6.2 diesel Chevy and a 700R4!

Like Clinto, I prefer the Multifuel. Second to that would be the 5.9 B series Cummins. There are a couple of 3208 Cats out there too. If you want really good power in a reasonable package, get the 5.9.

You'll notice, as I have, that these guys have a few inside jokes that are worth doing a search on to learn the origins. Especially the Blazer axle references.

I edited that to the 5.9. they were in a lot of school busses that has them with the trans. 2-3k for the whole thing. just need 12v and fuel to run it. I would make a duel system like the cucv has. you can change out the turbo and or injectors to get good power increases. I plan on putting one in my M810 in the next couple years

I would go with the 5.9 because you can build them up and they have lots of parts and aftermarket parts and reletivly cheap. plus they will fit under the hood with room to spare.
I don't know if there are better engines, but that is what I would do.

The only 12v part on the 5.9 you should have to swap is the shut down solenoid. You may be able to adapt the 24v one off of the 8.3 CTA in the 939A2 trucks or if you check with Cummins there may be a 24v application listed. You should be able to make the gauges work with a few adapters from the hardware store to intall the sending units or capillary tube.
