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?

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?

My ‘54 F100 was built in June ‘54. My buddy has a ‘54 F100 built in August ‘54. Both were built at the Chester PA plant. Both are EBU blocks. I’m convinced the 13 tooth distributor is large camshaft bearings and the 14 tooth distributor is the smaller camshaft bearings.

THANX! for that info!
This is the first concrete reference I have come across that the EBU was also installed in 1954 LT. It is randomly referenced in the TRUCK MPC but original parts info was deleted from later versions (updates) as parts availability dropped. You would need an exact period text to ascertain all the details. It (EBU) is also not mentioned in my 1954 TRUCK WSM, only the EBV.
There has to be a SERVICE LETTER somewhere explaining all of this. There are also many references in the MPC for converting the EBU to EBV for later service replacement.
Correct for camshaft DIST drive gear count.

Yes, thanks for that info Dennis. It helps shed some light on my car, from an originality perspective. I recently bought a refurbished 14 tooth distributor. It's part numbers all seem to match the numbers on my current EBU distributor, so the info I'm getting from from everyone seems to fit.
