What would be the correct cast code for a 289 engine that came out of a Mustang? I have a 289 with a cast of 0 C5AE 6015 E

The date code reads May 23, 1966. Shouldn't a motor that came from a Mustang be C5ZE 6015 E? And the code above coming from a Galaxie?

What is the letter O or number 0 mean before the C5AE?

Decoding Ford casting part numbers

Hello. The C5AE-6015-E is correct for your car. There were no ZE blocks. Since it's the same block as the 289 in any other car that Ford a 289 in, there wasn't any need to complicate things and make seperate blocks for each specific line of car. It was also the same block for the 66 model year. No reason to change the number, since they didn't change the block.

The same block was also used in '67. They were cast in Cleveland. Not that all 289 blocks for those years were that number, but that number was used in all 3 years and in every kind of Ford car that would have had a 289. Since Windsor didn't start making 289s until '66, the Windsor blocks for 66/67/68 started with C6.

Quite often there was what looked like a slotted, flat head screw head in front of, or after the casting number. If its not cast very well, or the casting is dirty that can look like an 'O'. It probably was a flat head screw that held the number block on the core they used to cast the engine.

Hi again. Yup. For a C code or A code car, the block could have had that C5AE-6015-E, or, it could have had C5OE-6015-A, or, it could have had the C6AE-6015-C, if it was a 66 model car. The K codes all had the C5AE-6015-E If they were 6 bolt blocks.

Wow...I'm quite impressed with your expertise on this topic. R U a ford Engineer Veronica?:smartass:

 

[Veronica]

Hi again. No, Ivy66GT is the engineer. :gringreen I just really, really like old Mustangs.

 

[Ivy66GT]

No, Ivy66GT is the engineer.

I never worked FOR Ford, just worked ON my Ford(s). I'm an aerospace EE who started working on old Mustangs because it was NOT what I did during the day.

Thanks for all the help. I did think that the engine I had came from a Mustang. However, I saw this;

eBay Guides - Decode your 65 66 67 68 69 70 Mustang Engine Block

And it talks about other letters on the block to identify which car they were from. Am I missing something here?

Ivy66GT, You mentioned about a slotted flat head scew on the block. Mine has that at the end of the 6015E _ And it definetly has a 0 about two spaces before the C5AE. Date code at the same location is 6 E 23, (May 23, 1966).

6015 = Designates an engineering number used by Ford.
"6015" meant "289 Engine Block"
I don't think so, this guide is not even right.

 

[Ivy66GT]

The magic word there is 'designed'. The letter says which car model was the intended use for the part being designed. That doesn't mean it wasn't used on every other model as well but it was DESIGNED for a full sized Ford. When every model used the same block Ford wasn't going to do any extra work to number them all differently. When the guys in the foundry poured the block it is unlikely that anyone even knew what kind of a car it was going into. Parts is parts.

6015 is a generic Ford number for an engine block, any engine block. Its not specifically a 289 engine block. So, yes, by saying it was a 289 block they were not correct.

On page 5-9 Bob Mannel has pictures of two C5AE-6015E casting numbers. One from 5B20 has no 'O' but the other one from 5B6 includes a leading '0'. It is on the other side of a screw head from the leading 'C'. He doesn't even mention the '0' and likely no one knows what it meant, if anything. Somebody in the foundry maybe liked zeroes?? Although it would have been an interesting job for the first few hundred, by the end of the month pouring block castings likely was, and still is, pretty boring work.

Thanks Ivy66GT, That's very interesting what you said. I Have heard many different stories about Ford and the Mustangs back then, (64-68 years) and it doesn't surprise me. "Parts are Parts". I heard when they ran out of 289s half way through the 68 car build year and started using 302s, they found about 600 289 blocks about 2 months later and put them in the 68s to get rid of them.

Thanks again,

Greg

0 c5ae-6015e

I would like to know as well why my casting number begings with an '0' it's 0 C5AE-6015E
Here's a link to the picture for all of those who say they would have to see it.

I remember reading about the "0" a long time ago when I was researching by block casting code, but I don't recall exactly what it meant or where I read it...

Mine has it too. My date stamp is March 9, 1966 so we know they were adding it at least up til then...
