When the Dearborn Iron Foundry (DIF) was shut down is when the "352" castings stopped. It was during 74 when they finally shutdown. The Michigan Casting Center (MCC) came on line in the early 70's and all (except the 427 and 428) FE block castings were then cast there and had the reverse "105" on the blocks. Both the 427 and 428 blocks were cast at DIF until they were no longer produced. The Cleveland Foundry (CF) was used for FE blocks for a short period of time and it's where most FE service heads were cast well into the late 70's.
Thanx...I sure do see a lot of "E"S on this block...thats why I was curious. So far what I found on the block for castings is
25 352 28 (or 29) DIF E1 E83 8E4
Any ideas what I have?
When did they stop putting 352 on blocks? Does that mean that it is a big block for sure?
FE's are big blocks, but there are lots of those. You have to ID the series. If FE, then you have to find the bore, then the stroke, as they all pretty much look the same from the outside. As per previous post, you will find "352" on all of them up to a point. It does not mean it's a 352.
To better answer your Q there were still 428 blocks cast into 74 at DIF. Many of these were still used in industrial apps. These have the "352" on them. So 1974 was the last year for DIF. The rest of the numbers like the 28-25 are part of the mold numbering system. As far as the E1 goes I've heard there were both East and West casting lines. So E1 would have been cast on the #1 East line. This was done to pinpoint mold and casting flaws and pull the offending molds offline for repair or replacement. 8E4 is the date code of 68-May-4th. As far as what block it is measure the bore size.
BTW John is correct on the "big block" being a Chevy term. It's something that has been just used incorrectly as a universal term over the years on all other makes.
While it may have started with the Chev engines, it is a generic term. Both GM and Ford sites--corporate sites like Ford Racing--use the term and it is not trademarked or copyrighted.
It's generally an engine with a deck height over 10". Purists that you are, I suppose you would never concede that a 289 is a small block, a 390 a big block, and that many many many people used the terms in the day when, for example, those were the only two V8s in a Mustang or Cougar.
So when someone asks if an FE or a 385 is a "big block", you would tell them "No, they are large blocks?", or "Size doesn't matter with Ford."
To reach another point of agreement, it is almost useless with the variety of engine series used by Ford.
Anyway, the OP question about "352" cast on the block--another Ford feature that has had heads scratching for 50 years, and will continue to confuse and confound for years to come.
