Someone Help Me With Engine ID Number!!!
Guys I was looking at my truck tonight and trying to decipher exactly what engine I had in the truck. It was kind of hard too see but i swear it looked like the block had 352 on it. the place i spotted it at was a little bit down and left of the right cylinder head, it was between the water pump and the right cylinder head.(facing the truck) it was not that easy to see, but is that how a block is identified? i thought it would read something like C8AE, a four digit code. can anyone help me out. If i did read it right, is the motor I have a 352 FE??

Here is some information I found that might help.
The 221, 260, 289 were originally designed for the Fairlane and produced only in the Cleveland engine plant from 1962-1965. The 1964 289 casting number for all 289s was C4OE-6015-C (later an F suffix). In 1965, this number was changed to C5AE-6015-E for the 289 2V, 4V and Hi-Po (note the change to full size Ford designation and 6 bolt bell housings). In mid-year 1966 the Windsor plant also began producing 289s. The casting numbers for these were (C6AE-6015-C with a "289" and "WF" in the lifter valley. In 1967 both Cleveland and Windsor produced 289s using earlier year casting numbers but with updated date codes. These two blocks were interchangeable, but there were probably some minor differences. Near the end of the 1967 production run, Cleveland ran out of 289 blocks and substituted their new 302 block, C8-OE-6015-A and marked with 302 in the lifter valleys. This block wasn't intended to see action until 1968. Note these 302 casting numbers returned to the intermediate size Ford or Fairlane lineage. Hence, a late model 289 coming from the Cleveland plant might have a 302 block with 289 innards. The Windsor plant had an abundance of 289 blocks for 1967.
In 1968 Cleveland only made 302s, while Windsor continued with the 289s. It appears Windsor also tooled up for 302s but the plug was pulled before they got to make any. They did however, design and produce a 302 block that was used on 289s after the stock of 289 blocks was depleted. The number was C8AE-6015-B with 302 marking in the lifter valley. At the very end of the model year some additional 289 blocks must have been discovered as the older C6AE-6015-C blocks appeared again. In 1969 Cleveland continued with 302 production. Windsor dropped 289 production and took up the 351. In 1970 Cleveland came out with its newly designed 351.
In short:
C8AE-6015-B is a 302 block from the Windsor plant that was used in 1968 on a 289.
Im not an expert at much, I hope Im not giving you bogus info. One of the other guys might be more help.

Goobzilla is correct. Most (but not all) FE engines have 352 cast into them. So you can't tell by that what the displacement is.
Unforetunetly with Ford, the same block casting number was used with a few different displacement motors, so even getting the casting number won't in most cases help id the engine. Unless the block was made specifically for a certain application and is unique to that size (such as the 406, 427, 427 SOHC and 428CJ blocks) the casting number will not 100% identify what engine you have.
if the motor is unmolested and 100% original, there should be a metal tag bolted to the distributor hold down bolt that has the cid on it along with other info for that engine. but they usually disappear years ago.
behind the starter should be a casting number (again not always) that will at least narrow it down to a couple of possibilities.
the only 100% sure way is either thru the ser# of the car that it originally came in or by measuring the bore and stroke (of course requires removal of head).
C8AE is a generic part # that breaks down as follows
C = 1960's
8 = 1968 (does not mean built in 1968, but means the year that particular part was designed or modified by engineering)
A = car line originally desined for (A i think means full size car)
E = engine component
so C8AE can really apply to any engine part designed in 1968.
looks like a little more investigation is required.
