I found a 4bt today
The bellhousing adapter is a good way to tell the origins of the conversion. A GM setup will have the characteristic "peaked roof" pattern. I have seen the Ford conversions used the 302/351W pattern.
Pics of a Chevy setup here with the 465 trans.

The NP435s used in the 67-72 Chevs were an oddball. 1st gear was in the 4:1 range... not a granny gear. Alum top cover as others stated. The couple I have found were almost destroyed internally. Not easy to get certain parts for because of the rare ratio sets.

The smaller chassis is the Chevy P-20, the larger is the P-30, useful numbers for sourcing parts. The truck in 1st pic looks like a 17' Grumman, on a P-30 chassis.
4BT is the 105hp/295 torque model, and 4BTA aftercooled is 120hp ad maybe 320+ torque as mentioned. The engine will have a CPL tag on upper left front corner of timing case to tell you all about it, what model, which injectors, which pump etc. Probably a CPL 858 VE pumped, but a few other possibilities there.
All Chevies that I know of had the engine tilted to the side, but hardly noticeable, you wouldn't see it at a glance. I mean it ain't like a Slant 6 or anything, maybe only 10*-12* or so.
I believe most Chevy 4 speeds would be SM465. I agree, an NV3500 can't handle the torque at all. NV4500 is the preferred choice, far stronger trans & still a 5 spd. Even then you want the Dodge NV4500 & not the Chevy model because Dodge has the heavier input shaft etc. Best to use the upgrade roller pilot bearing in flywheel too.
Trans failures are one of the top reasons big outfits like Frito Lay decided to dump all their diesels & go with gassers. 4BT's in Grumman chassis ate the built TH475 Pontiac trans so that should give an idea. I'd hesitate to use an A-518 too, much better choice of A-618. At the least the A-518 would need more torque converter, and specifically for a diesel, not a gasser.
Even though they're all aluminum body you've still got a whole bunch of truck there because of chassis & drivetrain components. If towing it you'll have no brakes like you would with a trailer, so....
One thing to be sure & keep is the all aluminum 32 gallon fuel tank, which fits perfectly between Dodge frame rails! Also get all the fuel line, supply & return. Also be SURE & pull all the Hydroboost brake assembly! Get the Lord Hydrolastic motor mounts too.

Cool, hope it works out for ya!
Folks have a hard time believing me and on another forum I've been called a liar flat out to my face, but what the hey > My roughly 6,200 lbs '67 Dodge D-200 Town Wagon with fairly stock 4BT & NV4500, Dana 60HD with 4.10's, 285/75-16 tires pulled 32 mpg under bad conditions including strong head winds, rain, snow, sleet & mixed mountain & flat lands running! That 32 gallon tank really gives it some long legs! Can't imagine what one would cost to have fabricated!?
If I can be of any assistance on 4BT stuff feel free to PM me.

Sorry to say I don't! Never did a web page. I do have some pics but will have to see about posting them, or put them up in Photo-Bucket & do a link or something. I'll put that in a new thread if I can figure it out.
i have a friend who is in the process of doing a 4BT install into an old toyota 1ton boxtruck the ones uhal used to have he is making a car hauler pretty neat lil project i think not sure what tranny he is gona use but his idea is a 4BT in this lil low toyota dually pulling a fifth wheel hes gonna go like me only run 2 cars an is guessing some pretty amazing MPG's with his lil bitty hauler ill try to get pics from him on this deal ....i never even relized toyota made a dually let alone a 1 ton so im even awaiting the finished project to hit the streets .......an just think to quote my wifey " awww look how cute the lil cummings yoda is gonna be " ....

It just floors me that American vehicle manufacturers don't build small-bore diesels. The only reason I can think of is that petroleum companies are throwing their weight around, squashing any diesel ideas so they can sell more gasoline to consumers who get pathetic mpg's, meaning a bigger profit for them. ...yeah, I'm a bit of a conspiracy theorist.

KD 93 I agree i went to the Dominican Republic a couple of years ago for a missions trip and all the trucks around there were little toyotas and nissans with little 4cyl diesels. I know not american made but man i would think people would buy them up in a hurry around here..........dont worry i think a lot of people would agree with you on your conspiracy

I just wish GM or Dodge would come out with their litte V6 or even V8 turbo diesel in a 1/2 ton pickup.
My dad would definely buy one He doens't need a 3/4 ton truck he just wants a diesel!
