By darrell - 2 Weeks Ago ever see one.just when you thing theres nothing new.over on facebook theres a block B4AE which looks like a 239.im sure it is.i know about the B5AE a 272 replacement built in 59 but never this.maybe its been on here before and i missed it. By KULTULZ - 2 Weeks Ago Is there any way you can take a screenshot of the CASTING ID NO (if shown) and post it here? I am inner-screen illiterate and cannot deface book. The THREE CHARACTER ENGINE PREFIX was used (EBU - 239CI DEARBORN) - EBV - 239 CLV) until 1959 when FORD went to the newer P&A PN SYSTEM. By darrell - 2 Weeks Ago its nice and clear B4AE over the oil filter.the front pulley is solid cast like all 239. By KULTULZ - 2 Weeks Ago Can you post where you found it on FACEBOOK? I will get my LITTLE THUMBSCREW to find it for me. Did you see either a DIF or CLV CASTING ID and a DATE CODE? By darrell - 2 Weeks Ago its under y block site yesterday.i cant move pictures from one place to another. By charliemccraney - 2 Weeks Ago I'm going to guess it is this one https://www.facebook.com/groups/fordyblock/posts/hey-could-anyone-help-me-identify-what-type-of-motor-i-have-all-answers-are-grea/10162545707417638/ By darrell - 2 Weeks Ago right on.im wondering if ted ever saw one. By 55blacktie - 2 Weeks Ago Could it originally have been a marine or industrial application? By KULTULZ - 2 Weeks Ago THANX! for that Charlie ... Maybe Ted has some insight. By Ted - Last Week No particular information on my end regarding the B4AE-A designation on the block.  Likely a service block and being from a truck, a replacement for an original engine.  A date code from the block would help to nail down the exact year the block was actually cast and suspect it was in the 1957/1958 era.  That was the period of time Ford was switching over the casting number nomenclature from the old system to the new. By KULTULZ - Last Week The CASTING ID NO location indicates a CLV BLOCK. The CASTING ID DATE CODE can narrow it down further. By paul2748 - Last Week Ted - the question was on a B4AE block ( see pic), not on a C4AE.  Seems to be a 239 block.  This seems to be a big mystery that no one has seen before   Ted (11/10/2024) No particular information on my end regarding the C4AE-A designation on the block.  Likely a service block and being from a truck, a replacement for an original engine.  A date code from the block would help to nail down the exact year the block was actually cast and suspect it was in the 1957/1958 era.  That was the period of time Ford was switching over the casting number nomenclature from the old system to the new. By Ted - Last Week Paul.  Good catch on catching what was a typo on my part.  I did mean B4AE and have gone back and corrected that.  The rest of the statement still stands.  There's a good chance that engine is a 239 but it will take a tear down in which to verify as the 256 engines shared the same bore size. By KULTULZ - Last Week There's a good chance that engine is a 239 but it will take a tear down in which to verify as the 256 engines shared the same bore size. Which makes me think that the block is a later SERVICE REPLACEMENT for the CLV 239/256 as was the B5AE for the 272 (later service replacement). This block was most likely the first one noticed. Need the CASTING ID DATE CODE By darrell - Last Week same crank ted not bore size By Ted - Last Week darrell (11/11/2024) same crank ted, not bore size Wish I could say I was testing you, but you are right.  The 256 and 272 engines shared the same block while the 239 and 256 engines shared the same crankshaft.  A bit of brain fade here on my part.  Thanks for the catch.
