V8 engine block mystery?

I have heard of two different stories of Chrysler 318's that have a International Harvester emblem cast into the side of the block?
One engine block was cast in 1976 and the other was somewhere around 1980 or 81.
The guys that have these blocks know it is a IH logo and that they are real Chrysler 318's pulled from Dodge trucks. So what was going on in the mid 70's to early 80's with IH and Mopar? Does anyone know some more info about this? This is very interesting!
 
mopar put engins in a wide series or ag equipment. my brother in law helped me remove a 318 from a combime to go in my 74 dodge van. the cam was ground so engine would run in reverse from a auto engine(or something like that,many years ago). d.coleman
 
Back in my days as an AMC-Jeep parts manager in the late '70's, we got in several parts--such as 6-cylinder AMC manifolds--with an IH logo cast into them.

My guess is--and, mind ya, it's ONLY a guess--that an IH foundry, such as the one at the Louisville Works, was contracting some outside work, and since the IH Scouts were using AMC engines as their ONLY six-cylinder gas motors in this era, it might've been a deal where IH was trading a product rather than spending cash.

BUT...as I said, that's only a guess.

As far as MOpar and IH go...didn't some of the bigger Dodge trucks use the large IH V-537 engine, at least in the early '70's? Might've been the same sort of trade-out deal. AGAIN, just a guess.
 
Pickups, Travelalls, maybe more --before 1970 used Borg Warner automatic transmissions I believe. After this, they used torque flight automatics from Chrysler.
 
Manufacturers often contract with each other to get product that couldn't be produced internally from outfits with temporary excess capacity. Harvester probably had excess foundry capacity and a need for ready cash that capacity could generate. You just didn't read about it on the front page.
 
My dad's 1967 model 1100 IH pickup had a torqueflite in it. Went through 3 of them using the truck for a lot more than it was made for. He finally had it changed to a 4-speed. Tough old truck.

I tend to agree with this assessment. There was a time when a lot of older foundry equipment was getting worn out and rather than replace that equipment, if there was a company that had excess capacity, it worked well for both companies.

Along that vein, I know a guy that worked assembly at IH. They sometimes received tractor front axles from the Deere plant across town. Painted green no less. Of course the Deere plant used what they had to protect from rust etc and it was going to painted again anyways.

Buying product from other manufacturers is a way of life, especially with complicated assemblies like transmissions. Too many patents to avoid when trying to roll your own.
