Thread: block number

Tweet

Wow that first pic sure did look like the C7SE-A number huh?? A little wire brush revealed the C7ME-A number clear as day. I have the same casting number on my block in the Coug. That said casting numbers are generic on most blocks. Once you pull the engine you'll see exactly what you have. And find the date codes that'll tell you a bit also. I'll decode them for you and you can compare it to the build date to see if they jive. My car has a Jan 8 68 San Jose build date. And the engine date codes are Aug 67. I've been told it's very possible it's original due to the strike and backlog of cars. Diverter valve has a Dec 67 date code as well as the smog pump which were added on at the SJ plant.
Once you pull the engine you can drill bit test the blocks cyl wall cores. Easy to do and that will tell you if there are std 390 or thicker 428 wall cores. You simply knock out the 6 freeze plugs in the block and use drill bits to gauge gap between the cyl walls inside. 17/64" is std 390 and 13/64" is 428. The date code for the block is below the oil filter adapter pad. Look for a number/letter/number(s) sequence. Head date codes are under the VC between the center 2 valve springs. Also note the head casting number between the center 2 spark plugs. The crank stroke you can either measure or see what numbers are on it. The 2U 390 crank is the most common to find. Very good too!

Denny thank you again also . I did find the info here doing a google . This site had the most description also of any i read last night . Most where bits and pieces .


FFR it did to me also but the wire brush took good care of the S LOL. Also a few spider webs around there . The number does show up more for a 428 catagory and if its thicker that will be good . Read alot where the 390 is a bullit proof block mostly in stock form and a clean up bore may be required . I also read where the bore on this block is what determined its CI and was capable of being a 428. Ford did alot of things that a book will not have straight up info on . Its the guy with experience in the garage from the time who has all the true facts that are not on pages.

My car is a '67 Falcon, both engine and cylinder head ( well it WAS, but it has been replaced with a D8 head ) are 1966, I was told that Ford used engines made in the prior year on some cars. the 1979 Merc Zephyr I robbed my D8 cylinder head, had both a D8 casting on the head and engine, valve cover emissions sticker had a D9 code on it, and the door date was 1979.

Also, my '67 has a gas pedal pad with a D5 date code. They was just trying to confuse us I guess.
