46 original "go devil" engine

 

The military jeeps were produced based on interchangeability, and that carried through fairly well throughout.  That said, get beyond the early chain drive stuff and the "minor" variations are bolt on.  Still interchangeable, but sometimes requiring staying along a line... for example, same basic gear drive block, but a different starter requiring a different bell housing and ring gear, or same basic gear drive block, but with an intake with the studs 90* out, requiring a different carb and linkage, etc. etc.  Later blocks have additional holes for later bell housings, but can accept earlier bell housings...  The permutations are too many to list here, but the same basic engine core throughout.  You'll find MB engines in 3As... my 2A came to me with an L134 out of a Kasier Henry J sedan with a kaiser supersonic head and 2A bolt ons (distributor, intake, starter, bell, etc), and now sports an L134 RMC M38 crate motor with an CJ3A head with an extra water port added, M38 style, and sealed bell housing to accept a 12V starter on a different ring gear...on and on.

The block and internals are largely the same with minor variation, the bolt ons are project specific with numerous variations 

A couple thoughts if there were still 134L's crated from the factory most likely they would be the last version of the engine used in the DJ-3A's (2 soft plugs on the side of the Block) not ones from earlier years. The 134L was made at least up to 1964.

In about 1975-76 I saw an engine in a crate with a for sale sign stapled to it. I stopped and took a look it was in fact a Military Surplus 134L complete with government tags on the crate etc. I asked the seller about it he told me his Dad had bought it many years before to make an Irrigation Pump out of it and never got to the project. They had sold off the farm and he was trying to clear out his garage.

The Crate was pallet style with no solid sides just a frame work of 1x4's the engine was filthy from years of storage. It was complete as I remember fan to flywheel carb and distributor/ generator no starter that I remember.

As the engine in CHUG was running fine at the time and as a High School kid (even working every summer since I was 5)  I didn't have money to waste on an extra engine I passed telling my dad about it who also wasn't interested.

From the way the guy talked I would have guessed the engine was bought via some sort of surplus in the late 50's early 60's

He was asking $250 I think.
