Early 1954 Ford Y Block vs Later 1954/1955

[motorman8467]

According to John Mummert's casting chart for Y blocks, the designation for EBU is for early 1954 cars, large cams. The designation for EBV is for 1955 trucks, small cams. My question is were any EBV 239 trucks made in the Dearborn plant in early 1954? If so, what was the 3 letter designation, and how can you tell the difference as opposed to the later version of 1954 and 1955 versions. I have a 239, EBV and EBV is stamped all over rhe engine, but no casting marks , or, date codes from either the Dearborn, nor, the Cleveland foundry. The spark plugs are the 18 mm ones, which is one indication that this engine is the later version. Water pump is the high pulley style, and part number crosses over to a 1955. Anymore information that I can get on this will certainly be appreciated.

As far as I know, I have seen no documentation of an EBV from the DEARBORN PLANT. The EBV was produced in CLV and was the precursor to the CLV 256-272-292.

There are no foundry markings at all, either @ the DIST or around the oil filter area?

from what ive read over the years thats about the size of it.

Not a single one on the block, however, one of the components, namely the timing cover, has the Dearborn (DIF) mark. Could the timing cover have been produced in Dearborn? The timing cover also has EBV 6059 G stamped on it. The intake has EBV9425 D stamped on it. Tranny is a AF7006. There is also EBV stamped, and only partialy visible sticking out from under the exhaust manifold gasket, on each side, but can't see the whole number without removing the exhaust manifolds.

There is something missing on this whole timeline, but I just can't seem to crack it.

There are differences and similarities. Some components interchange and some are unique. You know about the cams.

The WP was different also. Yours is a HIGH-MOUNT which was released I believe for a heavier truck than the F1.

There were few that understood the differences until a few years ago.

I think the EBU DIF was first design and when the CLV plant opened, it went with later TECH (EBV and following 256/272/292).

Is there anything specific you want to know? One would have to do a spread sheet with info drawn from the CAR - TRUCK MPC's of that era to nail it down. You would also need appropriate year WSM's and SERVICE LETTERS.

The EBU may well have been installed in an early 1954 F-SERIES but I have not run across an example. Most are 256 and 272 retro-fits when they go on the forensics table.

When you say "stamped" I assume you mean embossed in the casting and not actually stamped after the casting was made. It can be a point of confusion.

Thanks, for your input on this.I will add it to my compilation of material on this subject. Think I'm going to pull my distributor and count the teeth on the gear. I think that will get me where I want to be on this. Thanks, again. Always glad to hear from you.

[motorman8467]

Sorry for the confusion. I did mean Embossed. Thanks for pointing that out.

Here is a brief synopsis. Take with a grain of salt as this is most likely ones' opinion -

The Ford Y-block began in 1954 at 239 cubic inches and 130 hp. The engineering and service departments' prefix nomenclature for this version was EBU. It was equipped with a two-barrel carburetor and a single exhaust. The bore was 3.50 inches, and the stroke was 3.10 inches. The compression ratio was 7.2:1. (The individual components of this version, as well as for all other Y- blocks, will be discussed later.)

An EBV version, which also displaced 239 cubic inches and produced 130 hp, was used in F-100 to F-600 series trucks. This version was similar to the EBU but featured a heavy-duty air cleaner, rear sump oil pan, special truck carburetor and distributor, chrome-plated top piston rings and a heavy-duty flywheel. The dipstick was relocated to the right side of the block. An extra mounting bracket and a double crankshaft pulley were used for a four-bladed fan.

During 1954, all 239-cubic-inch passenger-car engines and some 239 truck engines were built at the Dearborn engine plant. At about the middle of the model year the manufacture of 239 cubic-inch truck engines was transferred to the Cleveland engine plant. In 1955 all 239 truck engines were built at Cleveland.

Not all parts, however, were interchangeable between the Dearborn engines (both car and truck) and the Cleveland engines. The cylinder block assembly, block, heads, head gaskets and camshafts on the Dearborn 239's were not interchangeable with the respective parts on Cleveland 239's. The Dearborn-built 239 used a "large" camshaft with a thirteen-tooth distributor drive gear and bearing journals 1/8 inch larger in diameter than the "small" Cleveland camshaft and all other Y-block camshafts. The Cleveland- built 239 and all later Y-blocks used camshafts with a fourteen- tooth distributor drive gear. (Parts interchangeability among 239's is addressed in the service bulletins section of this book.)

Ford's EBY version, which came out in 1954, was the Police Interceptor engine. It displaced 256 cubic inches with a 3.62-inch bore and 3.10-inch stroke. With the four-barrel carburetor and dual exhaust, this engine produced 160 hp. The right-hand exhaust manifold was capped in front where the crossover pipe would have attached. A redesigned left-hand exhaust manifold was used. The compression ratio was 7.5:1.

An EBZ version, used in F-600 and F-700 trucks and school buses, was a sister to the EBY. It utilized the same bore and stroke dimensions to yield 256 cubic inches. The EBZ, however, produced 140 hp with a two-barrel carburetor and single exhaust.

Can you clear this up for me? In your last post reply you stated that during 1954, all 239 passenger car engines, and SOME, 239 TRUCK engines were built at the Dearborn engine plant. What engine designation was used on those TRUCKS that were built at the Dearborn Plant. Were they EBU, or, EBV. Just wondering.

If you want more confusion, check out the Mercury 256 for 1954. There is a lot of stuff on the Y-block forum for the small versions of the Y-block. The Y-block guy has all these numbers.

Thanks, I will take a look. I've always been a Mercury fan. Took my driving test in a red and white 1957 Mercury convertable.

I didn't state, I gave a reference that stated such. Where the writer got his info was not stated. It is a gray area.

Now I have a 1954 TRUCK WSM and that manual only refers to the EBV 239. I will have to check the publication date on it but had the EBV info only. If FORD also built the truck 239 @ DIF, that service info would have to be included. The EBU came before the EBV.

Their (?) ... There is no CASTING ID anywhere on the block, heads, exhaust manifolds, etc. (I showed location examples)?

Get' em 3rd Grade Education ...

Something like that would be consistent with a lot of Ford 1st year of production stuff. FoMoCo was busy building several new manufacturing plants in the 1949/55 time frame. The 1949 models were a year late as it were and even later for stuff like the automatic transmission. Harold Youngren and others were busy trying to build the new shoe box Fords so the transmission took longer. He had a lot to do with the design of the original FOM/MOM transmissions since he was involved with the design before he left Borg Warner for Ford Motor Co back when Hank the Deuce was hiring all the new people to help him run things. It was just a few years later and the new 215 came on line then a few more years and they were making the small Y-blocks engines.

The Cleveland engine plant No.1 started coming on line in 1951 for the Lincoln & truck big Y-blocks and then plant No. 2 came on line for the 1955 Thunderbird and Mercury 292 V8. Ford spent a lot of bucks in those years just to keep up with the times.

I have a 1954/55 truck WSM, and just the engine and transmission, and the only things I can determine is that my EBV engine is a Truck engine, with the High mount cooling fan, double groove pully, AF 7006 3 speed std tranny, 18 mm spark plugs, Load-a-Matic distributor, (special for truck), Ford E6 2B spl truck carb. I will have to tear down the engine to find out the rest. It was running when it was stored, so I would rarher get her ready to crank before tearing her down. Already rebuilt carb, so it won't take much. Let you know how it turns out. I enjoyed discussing this with you.

[motorman8467]

I would tend ro agree with you. I will be tearing this baby down soon.. Let you know what I find. Thanks for the info. Keep that Mercury shiney.

[KULTULZ]

If you can while it is on the forensics table ...

Record any and all CASTING ID and DATE CODES.

You will be helping a bunch of people.

Hold on a second, are we discussing a 1954 PASS CAR or F-SERIES?

[motorman8467]

The engine came out of a 55 F 100. All I have is the engine and the 3 sp tranny.
