Determining the Size of my Engine

I've been assuming that my V8 is a 239 but I'm not 100% positive. What is the best way to confirm?

If I remember right that the only way to tell is the casting number on the crankshaft. Since the block was used for the 289,302 and I think the 351 (not sure about the 351) so the oil pan would need to be removerd.

Once I cleaned my glasses I saw that I read it wrong.. 239 not 289...

According to this page:

TECHNICAL

The 239 'Y' block had the following casting numbers (on the block not the crankshaft):

EBU 239 cu. in. V8 1954 cars only. Cleveland and Dearborn versions.
EBV 239 cu. in. V8 1955 pickup, small cam bearings

WRONG engine family... OP was referring to a Y-block not a WINDSOR.
For the record, 289 and 302 WINDSOR motors used an 8.5 inch deck height and the 351W uses a 9.2 inch deck height. 351W uses a common design with the 289/302 but on a larger scale. 351C and 351M/400M engines are also completely different animals. 351C uses it's very own block and the 351M/400M share cylinder head design with the 351C but nothing more. W and C motors use a common bellhousing pattern (early 221/260/289 use 5 bold bell housings and later 289 and all 302 use a 6bolt bellhousing. the M motors utilize the same bellhousing pattern as the 429/460 385-series big block.

now back to the original question about the Y-block motor... I HAVE NO IDEA, sorry for the hi-jack.

I notice on the side of the engine, it references 8BA. Does that tell me anything?

Sounds like a flattie not a Y-block.

You didn't have many choices in 51/52. If it is a flathead it should be 239 ci.

Count the head bolts - 24 per head.

Yes, 8BA is a flathead V8. Originally 100 horse that block was used from 48-53 in the trucks and 49-53 in the cars. 8BA, EAB, 8RT, are all ford 239 flathead v8s

With a 60 year old flathead the only way to determine the size (Cubic inches) is to measure the bore and stroke - You don't know what previous owners have done , replacement, rebuild, hotrodded. - Pull a head and get out the measuring stick.

I thought that shouda been a flattie..... then went back and edited my post to say yblock ... then spent the last 4 hours thinking " a 239 is a FLATHEAD dummy..... Y blocks would be 272/292/312..... then I realized that the OP was in a pre-53 truck. then I felt like an idiot again...... then I checked in and...... here we are... I am an idiot.. LOL

Personally I"ve forgotten more than I know....... I think?!
