I ‘d like to get in on that, I probably should buy some of that inch drive Williams Proto Blackhawk mutt set up at the flea market that one of the used tool slingers keeps bringing up there just in case I get into something like this again. The real downfall of those early triple diamonds is the cast into the rod Babbitt rod bearings. They are rebuildable but you have to usually find a large industrial rebuilder to find someone that specializes in pouring and lapping Babbitt bearings. If the engine is locked, that’s almost always the cause.

I'll be finding out once it gets a little warmer. IM sure no one around here could do it justice. I like the idea of upgrading
 
Yeah, one advantage of a slant is that people give the things away on here on occasion if you come after it. I can’t remember the SAE classification of the bell housing to transmission pattern, but NP and B-W shared those the medium duty transmissions, I just am not to certain about 1950 though. Is that a T-18 or 19 style or have you been able to identify it yet? I know that as long as the weather doesn’t get into them, they stand as a monument to time itself. They used them in early school buses and all sorts of medium duty applications, virtually unbreakable.
 
Friend has a 1952 L122 with the SD220. Had to get custom rims for the odd 6 lug on 7.25 circle split ring rims Fun trucks! On the lug issue, I'm pretty sure they LH tread on the drivers side.

How is yours titled? Some of these old trucks used the engine serial number on the title instead of a body number. Might want to check on this before pulling the engine out of the frame.

I suggest an AMC/Jeep . 4.0L , or a 258 cu. in. Parts are everywhere and reasonably priced . Couple that with a Torqueflite trans and a 8 3/4"Mopar , Dana 44or 60 , 9" and you have a winner IMO . Just remember a 4.0L doesn't have a mechanical fuel pump but does have F.I.

I think its the T-18 the T-19 is syncro.
 
It's been too long since I've gotten to work on this kind of animal... that sounds right for that truck, I'll have to look at Novak again but I think there may have been a pre T-18 model but I can't remember what kind. That is one large five lug bolt pattern, what does it measure? Is it the eight inch pattern specified on american wheel specialists obsolete wheels?

I will check on the Vin. Title is only four numbers. LH lugs all the way , marked L on studs

I believe so 1 1/2" nut

Not planning on changing up rear end.
A lot of good ideas coming out here.

Already looked into upgrade on wheels. AWS is about 70 miles from me , they specialize in wheels big trucks. 19.5 that will fit a radial is going to run about $1600.
 
Ouch! I think you may want to look at some used military/nato type wheels, you may be able to score something that you just have to have redrilled at your favorite local fabrication outfit for less. I know 19.5 inch tires not gonna be inexpensive either though.
 
Might also check condition and availability of brake drums before commmiting to tires and rims. On my friends L122 they're made of unobtainium. Considering they're already cut thin and the bolt pattern, probably would be cheaper in long run to swap the rear. I know project creep and budget build....
 
I would go with a slant six without any doubt.

I have a 70 dodge D100 with a slant and I love it. I love the sound, the smell, everything about it.

Here is a video with a 1 ton dodge truck with a slant. It's so awesome

Thanks , that's one thing I hadn't thought about comparing cost of newer rear end to custom wheels. Swap has to be cheaper. I will look into that for sure.Not sure but I think drums will swap out to 70's IH.
 
Yeah, what you would save on custom wheels I could do a complete front and rear axle change in my area and alcoa 10 lug semi wheels, you wouldn't believe what people are hauling off for scrap around here anymore.

When my dad was a kid, their grain truck was a 64 d300 with a slant and that new process. Neighbours had the same, but with a 318 poly. Theyd always race to the grain elevator with a full load then home. But that poly had to stop to refuel. The slant, albeit 50mph full load, always got er done...and won!

What rear axle would I look for. Doesn't need to be International

14 Bolt GM's are usually cheap and plentiful as are truck Dana 70's. If you want to stay low, which I would with a six, and get some eight lug duallys in the process, look for a C-30 from '75 to '87, all the ones I have seen had 4.56 or 4.88 gears, and detroit lockers are fairly common, too. Of course, 8X6.5 inch bolt circles wheels are common as dirt in about any size you want. A retired step van bread hauler with an I beam or Dana tube front axle is your best possible donor vehicle, they are out there with disc brakes and you can get a matching system. Another vehicle to look at, an across the pond option so check parts availability and price if you find one, Mitsubishi/Fuso or Isuzu trucks. I don't know right off what the spring perch widths are but measure before looking. You may be get lucky (but don't expect to!) and find a direct bolt in. I would consider updating the springs at the same time as well.

I would probably pull everything. That's a good start.I'll see what's out there.
 
Looking at Dana 70's came across
a C-60 which by looks seems to be the same wheel and tire size as the L150
even rear looks to be the same size.
 
I keep forgetting that it’s an L-150, everything LARGE BY HUGE. I hope you can come across C50-C70 stuff as easily as I still can here ( even though the high scrap prices in ‘08 made everything the cleanest it’s been since World War II). I guess that’s at least a 1-1/2 ton rating? Check parts available by years, but I believe most C-60 is still serviceable through rock auto, even Napa. Big GM or Rockwell axles. An eighties GM based Thomas school bus will be your best friend, almost no demand for parts and steel Budd wheels too. Single speed axle ratios of 6.17 or 7.2:1. Most are C60/70 platforms. C60 enthusiasts page C60.com for tech. May be able to find something newer in the 10 lug pattern to get away from the Budd split rims, shoot for the cheapest tire availability. Most junkyards here use them for storage and office space, show up with a load of railroad ties from Lowe’s to put a couple of crib cages under each end and you can buy about anything you want, cheap if you make friends... If it were me, I’d cut the spring mounting bracket rivets and roll the whole mess home. When you get to a bare frame and everything cleaned up, whack all the rusted unserviceable springs, mounts etc. etc. and put them out to sale on Binder planet. May find someone that just has to have your old axles. If you go with a \6, do the Dutra split manifold kit (if you got room for the exits )and get an iron super 6 intake. I can’t remember the brand of \6 manifold gasket that comes up on here but use it too. All cast iron works best, and has the lowest maintenance on keeping everything tight and leak free in this heavy of an application. It’s going to pulling a lot of rpm and load at the same time, so the exhaust gas temps are going to be pretty high. Not that it matters a whole lot to a \6, I have mercilessly abused several and never broken one.

Remflex gasket!!!

Yes L150 is a ton and a half. You learn toward GM any reason? easier to get?
How about Dodge or Ford. I haven't hit junk yards yet , trying to figure out best fits . I need to take measurements. I can probably be a couple inches wider if need be as there is no fender wells
may have to move spring perches.
