I am sure this has been covered in the past, but what is a source for 239 cam bearings  I am trying to help a local shop out as they thought all Y blocks are the same.. I know 239s are different but never paid much attention to building one

What 239 - the early ones had bigger journals and the later 239's had the smaller journals that all later Y's used. Look for the block casting no's - the EBU used the large cam bearings and the EBV used the small cam bnearings

Were all the cam bearings on the early 239 the same OD?

no as was said the 54 car engine ebu had the large cam bearings.the OD was bigger as well.the truck ebv even in 54 had the small bearings.

Should have been clearer.. Are all the bearings in the early engine the same OD?  A local shop has an engine that the two middle bearings are .020 bigger OD that the other 3..

Looking at the specification manual, all five of the Ford Y cam journal holes in the block are the same size.  For the 1954 big journal camshafts the block hole size is 2.0505" ±0.0005”.  For the 1954 small journal camshafts and all 1955 and newer Ford Y’s, the cam hole size in the block is 1.926" ±0.0005”.

Don't want to hijack the thread, but I think my question will be helpful to all who find this a bit confusing. My ranch wagon was made in June of '54...pretty late in the model year, yet it seems to have the EBU 239. Everything I heard from the original/previous owners indicate the engine is original to the car. The intake manifold and (I think) cylinder head castings have EBU on them, but I admit I haven't checked the block castings (car is in storage.)

Is it possible they put EBU engines in cars late in the model year? I'd like to know for future reference in case I need to overhaul or tear into the engine. My car was made or assembled in Kansas City if that makes any difference.

The 239 CI EBU (DIF) was assigned to PASS CARS. The 239 CI EBV (CLV) was assigned to truck. Supposedly, the 1954 truck also used an EBU, cataloging shows it, but I have never read a post where anyone with a 1954 LT had one. It seemed it was either a CLV or later year mis-match.

Thanks a bunch, KULTULZ. Was the 13 vs. 14 tooth distributor gear related to whether the 239 had the larger or smaller cam journal bearings?
