The Nash/AMC/Jeep 6 cylinder has got to be close.
Wasn't the Crosley engine used in some standard issue military generator?
I bet the WWII jeep flathead 4 cylinder (go devil? or hurricane?)is still in production somewhere in Asia.
When was the first Cox .049 built?

Good call on the Cox. They were well sorted when I was a kid - and that was a LONG time ago.

I'm thinking Stokes is on with the Wisconsin/Continental/etc industrial engines. WE need to find one for sure, but some of those are OLD ass designs that were or are still made recently.

I know you could get a flathead engine powering an irrigation well pump as recently as 10 years ago, brand new from the factory making them, I will try to ask my buddy that runs them west of Omaha... he has his running on Propane.

I suppose it depends on what you consider longest design... they still produce small block chevrolets in crate versions.... heck they still produce flat heads..... brian - care to give us a hint?

Well, the 170 cubic inch Studebaker Champion inline 6 cylinder flathead engine came out in '39 and was still being used in Larks built in the early 60's. If I remember correctly, Studebaker even offered an overhead valve conversion of the Champion engine... I could be wrong on that.

In it's basic design, the AMC Inline 6s, I think they made those from 1958 to 2005?

I've heard stories of people taking their late 4.0s apart and still finding the old AM Script on parts of it

The Rambler/AMC six changed in the 60s, there are "early" engines and "late" engines, and they do NOT swap. btdt when I worked at the junkyard.

Kind of a neat subject!

I'm saying anything domestic counts...how's that for wide open? HA!

The Continental Red Seal engine (that powered my Worthington Tractor) was made for a long ass time as well.
