brushed the numbers better pic put in .
FFR should be along, the date code sure looks correct for the car, Bobby!
Dave thats what in hoping . I did readjust them from original post thought i seen something else . Had to wire brush it down .
From another forum:

C7ME-A Blocks can be a car 428 or 390/360. Easy way to tell is to pull out a plug (#1 would be the easiest to do). Use a long rod and measure the stroke. If it is close to 4" then you got a 410 or a 428. If it is 3 3/4" then its a 390. If it is 3 1/2"...... Well it could be a 360
Jack thanks it will come out and be torn down . I read a site where they claimed it the 330 or 428 also so maybe that means it could be bored out > heavier block maybe ??
Wow that first pic sure did look like the C7SE-A number huh?? :LOL: 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. :HMMM:
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.
Hi, with the information above i can almost figure out what moter i have but not quite. I'v had this truckfor almost 3 years now and still do not know exactly what i have under the hood. The Stickers on the aircleaner and valve covers say that its a 406 but my cousin claims that its a 390. I looked at the casting numbers on the outside of the block and beside the oil filter it reads"6G15" and then on the other side of the block below the #1 cylinder it reads"C6ME-A." And from the chart above it would mean it is a 390 or a 428. So if any of you'll have any ideas on finding out what it is let me know. If need be I'll post pictures. Thanks!!
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.Quote:

Matt sometimes parts were used for quite some time. The C8AE-H heads were used until mid 71 when the D2TE-AA version came out. And the D2 heads were used until 76 in production. Both were service parts for years after. My tunnelport heads carry a C7 casting number and are 71 service parts. Lots of parts on my Cougar are the same as your gas pedal. The part numbers were always upgraded in the books but in many cases the casting number on the part itself remained unchanged.
Cambo, welcome to the forum. Your engine could very well be a 390, 406 or 428. It depends on the blocks cyl bore size and crank stroke. The 390 has a 4.05 bore and a 3.78 stroke. The 406 a 4.13 bore and 3.78 stroke. The 428 a 4.13 bore and 3.98 stroke. You can easily measure the crank stroke thru the plugs holes. But you'd need to remove a head to measure and confirm to cyl bore. If the engine runs good don't sweat it. If you ever need to rebuild it down the road you can measure and ID everything then. Your block is a 66 casting. 6G15 is the date code of 66/July/15.
Thank you for getting back to me so quickly. If that engine is a 66' casting then why would it be in a 1972 Pickup? Now im not sure that it has not had a swap. It does not look like it but i might be wrong. Thanks again for the quick!!
P.S. If you have any thoughts on intake manifolds the information would be great!
Well it was replaced. If you can see the casting numbers on the heads and intake post what they are. On the intake it will be on one of the front runners. On the heads between the center 2 spark plugs. After 30-40 years just about anything could be there. Even a 360 as they used the same block as the 390 just a shorter stroke. Once you measure the crank stroke you'll have a better idea except for the cyl bore.
Ok now i have another peice of information. I got a rough measurment of a 3 3/4 inch stroke (if it were to be off i think it would be a longer measurment that i got) so that would rule out a 428 if i am reading right.
The #'s on the intake are.. 5D
C5AE9425C
The #'s on the heads are.. EDC-E
6090
and then off to the side of the head #'s are.. 79 N
Yep stock 390 stroke is 3.78" so your about right with your measurement. The intake is std issue 4bbl for a 65 352/390. Not a bad intake but heavy.
Then I wonder why there are 406 stickers on the valve covers and air filter, weird huh?
Well it could be a 428 block with a 4.13 bore and a 3.78 stroke. It's not an original 406 they were a 62.5 to 63.5 option only. And the blocks were a little different from the 428. But displacement wise you'd be a 406 with that combo. Or it's wishfull thinking on someone's part. Like putting a 427 sticker on a 390 if you will. If the stickers are round and gold, with black and white lettering/numbers they are original or original style repops. "406 High Performance" is what they would say. The valve covers from the 406's were chrome baldies. Worth a few $$$$ if so. Until you get around to pulling a head off it's a mystery......
Well, i'm planing on pulling off a head this winter so the mystery will be short lived.
Well cool! Give us an update what you find. Good luck!
