Default "Diamond engine"

Took my '29 CCPU to Sam at Arizona Model A yesterday. Sam took a look at it and informed me that it has a "Diamond" engine, which, even though I've been messing with these since the early '60's I'd never heard of. When I got home I did some research and discovered a code of K107 on the engine side. That means that it was built on 1 November 1937! Wow. It also has a stamp from a rebuilder (no longer in business) from Utah. Then his Dad straightened out a slightly bent right front frame horn using a high-lift jack a tool that I don't have. Took 5 minutes! No charge! I'm a happy camper.
When I bought the truck the engine was stuck but I took a risk. Got it freed up after laying a smoke screen in the neighborhood from Marvel Mystery Oil and Kroil, and now it runs great except the Tillotson carb still leaks.
Thanks Sam and Dad!
Ned

Sounds like you had a great day, congratulations, and a tip of the hat to Sam and Dad.

I've got a diamond B in the 28 coupe I just purchased. It's from the late Harold Johanson's estate.

Quickchange- Did you meet him when he took his A and friends to NZ? That must have been quite the neat trip. And yes, he's a very helpful nice guy. Best part is he's nearby! His Mom's always working.

Sammy's Model A knowledge is legendary and he is not backwards in sharing it. I've known him for quite a while now and he has been helpful right through. Sam and Bonnie too.

Got a '36 and 2 '37 B's .They have the latest revision done during production.Some,but not all have hardened exhaust valve seats. The diamond foundry mark has never been identified. Anything else is speculation.

I have a Diamond A engine. Were there any post production upgrades to them?

Does the 'diamond block' have the provision to mount the '32 & up fuel pump ?

I have a diamond A engine also. Is there any internal differences between the stock A motor to the diamond A.

Its the last design revision a late '31design
Ford made a number of block revisions during production,the late 31 incorporated all of them...difference? No,more like the best.
