Okay I just looked at an engine and I think it may be a 351 cleveland. I got some numbers off of it.

These were off of the intake manifold
D 4AE 8425-CB
D47h
P20E
843082 8A

CARB TAGE READ
AUTO LINE 0 879A

Thanks for your help.

 

Can anyone help me out on this? If it is the cleveland I really want it, and don't want to let it go to someone else for cheap. Thanks

Well - I looked it up in my book and 8425 is not in there - but 9425 is (those can be tricky to read). Unfortunately I could not find a definitive answer on the engine based on that. If the engine has a tag held down by the coil bolt, that will have codes on it that will tell you the year and the engine. Post the engine code from the tag and I'll try to translate...

OK - another thought - if you cannot get the tag number - get the block casting number. It should be on the back of the block above the starter. This should be more definitive than the intake casting number, but less than the coil tag...

The coil tag numbers for a 351C are:
600, 601, 602, 604, 606, 608, 609, 610, 611, 613, 614, 615, 616, 617, 620, 621, 625, 630, 632

The coil tag numbers for a 400 are:
219, 220, 221

Note that these codes are for Clevelands up to and including 1974. It is possible that they kept using the same tag numbers after 1974 but don't bet on it. Presuming no part swapping, we can presume that it is 1974 vintage or later based on the "D4". D says 1970's, while 4 means the 4th year - hence 1974. That does not mean that it is a 1974 engine - they may have used the same intake for several years. If you do get a tag or block casting number, post it...

 

Alrighty, thanks.

I'm under the weather so bare with me. From the top, 351 clevelands have dry intakes, meaning no coolant flows thru it, hence the diff between Windsors and Clevelands Clevelands also have a NUMBER cast in the upper corners of the heads, a 2 or a 4 corasponding to the intake, 2 or 4 barrel from new. 351Ms or 400s have a M or nothing here, but that doesn't mean much as they are interchangeable. Ms and 400s never came with factory cast 4bbl intakes, even though Ford did list the 400 4bbl in 74 I believe. Intakes are not interchangeable. Ms and 400s are much wider the Cleveland. Ms and 400s have unique engine mounts cast in the block. You'll have to compare with a small block to see the diff. Ms and 400s (except a few 400s)have the Large big block tranny bolt pattern. Measure the top 2 bolts compared to a small block, which the Cleveland shares. If I'm still alive, I'll check back to see how you made out.

 

its an M block, the last C block was D3 not D4, if i rem right. Here are most or all of the 351c casting codes.

Year Type Casting Part

1970 2-Bolt D0AE-A,D0AE-C,D0AE-E,D0AE-G,D0AE-J,D0AE-L D0AZ-D

1974 2-Bolt (CJ) D2AE-CA D1ZZ-A
1974 4-Bolt (CJ) D2AE-CA D3ZZ-A

HO = High Output
CJ = Cobra Jet
BOSS = Boss 351"

 

Here are the numbers off the block.

D2AE-CA

and I also found

3J22

So I suppose its a cleveland now I just have to figure out which one. Thanks for the Help Guys.

You have a 1973 4 bolt Cleveland block cast on sept. 22. Heads if origional should be 4 barrel w/ 2.19 intakes and 1.71 exhausts and open chambers at 75.5ccs

 

GT40's info said that there were no 73 4 bolts. Which one is rest. Thanks for all the help it is much appretiated.

Well - since D2 in the block casting number means 1972 and they started appearing in 1971, I suspect that the block came out in late 1971 and continued to be used through final production of the 351C in 1974. It is curious that it seems to apply to both 2 bolt and 4 bolt mains. I have never compared them, but I suspect that the raw block castings are the same - and only differ in the machining - 2 bolt vs 4 bolt. If so, that's why it was such a mix-and-match as far as which engines had 2 bolt and which had 4.

In the end - it really does not matter. Most engine builders will tell you that other than for all out racing, the Cleveland 2 bolt mains were stronger than the 4 bolt mains found in other engine families. If you were able to find the coil tag, or look at the serial number stamped on the left rear of the block, you would have a better idea exactly what year and engine you are looking at. The big concern should be the head and pistons.

Since the intake had a D4 code, and it is clearly a 351C which ceased production in 1974, you almost certainly have a 1974 engine (as long as we assume that the intake is factory). Next question - was it a 4v carb and intake? There were only two 351C engines in 1974 - a 2v with 8:1 compression and a 4v with 7.9:1 compression - no CJ or Boss. The pistons were likely the same - dished - and the difference in compression would be attributed to slight differences in (open) chamber volume. So - my opinion is that it is a 1974 351C either 2v or 4v, which should be obvious from the carb. Good luck!

 

Hi all,

I just scored a Cleveland. It has the 2v heads. The casting on the block is D2AE-??. I tore the heads off and it has flat top pistons.

The latest date I can find is D3 from the intake, which suggests it is at earliest a 73..

I thought that the 2v motors have dished pistons? Or is the only difference between the 2v and 4v the heads? The motor, from what I can tell has never been opened before.

Thanks
Riley
