Post ford engine identification

I am trying to identify a big block Ford engine I just acquired in an old mustang. I know it is not original. Casting number on back is 04AZ82A. Can anyone tell me what this engine is. It appears to be a 400 size or larger. thanks

I dont think that casting number is right. The casting number on fords is usually found on the underside of the engine. Its on the passenger side for smallblocks but im not sure for big blocks. Its a number with this format C9AE-8473-E

On my 460, as with all bigblocks, the casting number for the block in on the underside of the block, passenger side, middle to back of the block, four numbers/digits, four total. Mine is D1VE meaning D for 70's era, 1 for year 71, V meaning out of a truck, and E for engine. Now, if yours begins with a C, it of the 60's era. the heads on a 429/460 have there casting numbers just below the valve cover lip. Same thing applies with the casting digits here for year and what they are out of. Now, there will probable be three numbers/digits after bothof these casting numbers, these are your change codes. Most ford engines have these change codes, which identify the changes made, and what other parts you can interchange. Anymore help, just email at kwyoung@ndak.net Billybob

I just looked in my ford manual on how to rebuild big blocks by tom monroe. If your first digit is a D instead of a O, its a 70's. Then your 4 for the year 74. It's kind of dirty down there, clean it off and make sure. The third digit specifies what vehicle it's out of. "A" is out of a full size Ford. I made a mistake when I said mine was a "V" for a ford truck, "V" is out of a 61 and up Lincoln, sorry about that. Now, your "Z" must be and "E" for engine, it has to be, it's and engine. If your change code is "B2A" instead of "82A", your engine is a 1974 400 big block motor. Clean up your block real good and give me the numbers again, and I'll verify them, and I can then give you all the specs (Compression, bore, stroke, valve sizes, cam lift, everything). Give me the head casting nunbers as well, sometimes they swap heads like they did on my 460. Billybob

Hey guys,
you all seem to know what you're talking about when it comes to Ford engines and I have one that I can't identify. It's in a 66 Mustang that was set up as a pro-street drag car in the 70's. There is a badge on the fender that says 428 Cobra-Jet, but I'm not convinced that that is what the engine is. I'm not familiar with big blocks, but the intake manifold forms part of the inside edge of the cylinder head. The engine has been rebuilt so the parts may be mixed up. I can't find any readable numbers on the engine. Can you help me??? What do I need to look for to identify the block and heads and is this engine a good base for racing? Would really appreciate your help. I have some pics if that helps.

Question

[quote]Casting number on back is 04AZ82A<hr></blockquote>

Is the sequence cast or stamped? Are you sure the sequence is correct?

It is an FE.

Wow, I've spent almost all of the day looking for answers to my question. I understand that identifying these engines is not an easy task.

I've found some casting numers;
Block casting #; C8ME
Block date stamp: 8A25 (Jan' 25th 1968?)
Head casting #; C8TE
Head casting date; 5J25 (Nov' 25th 1965?)
The engine has an Offenhauser dual 4bbl holley intake manifold with the dual Holleys on it.

Does this help with further identification?

Many thanks, again.

Lewis

<a href="http://pliverman.home.mindspring.com/index.htm" target="_blank">-Here-</a> is a cross reference of FE casting numbers. Take it with a grain of salt as it is not an exact science.

[quote]Head casting #; C8TE

Head casting date; 5J25 (Nov' 25th 1965?)<hr></blockquote>

These two codes do not jive...please recheck.

The Offenhauser is a nice touch...

O.K. My mistake, I re-checked on the cylinder head castings and it looks like it's C6TE-G (the other head is clearer) & there are no other numbers following it. Any clues?

Thumbs up

The cylinder block is definitely a 428. The head casting numbers are a little strange. Let me keep on working on those.

OK...Here we go...found it.

C6TE-G was a 1966 standard assembly head used on the 352, 390, 410 and the 428 w/o Thermactor.

There is a note here that it is a desirable performance head, just a brief passage. They are definitely not Cobra Jet. The block is a 1968 and the heads 1966.

It may be possible the engine was built right before the introduction of the 428 Cobra Jet.

The engine will have to be disassembled to see what all is inside.

Hope this helps.

Really appreciate your help. I plan to tear down the engine real soon and check it all out. I'll still be using it for drag racing, so is there anything in particular I should look for?
Many thanks again. Lewis.

Use the above URL I gave you for possible CJ component identification.

I managed to pull the motor & tranny over the weekend and found what I believe to be Super Cobra Jet internals, the casting numbers of visible parts with only the oil pan removed are as follows;
Rods; C6AE-E
Crank; 1UA
Main bearing caps; C2AE
It has a large balancer weight behind the harmonic damper (Only SCJ should have that?)
If I'm correct, then that's really good news. I bought the vehicle as a 428 CJ and got a 428 SCJ.

Now the next question;
Is the head bolt pattern on this block the same as the 460 block, in other words, will a 460 head fit this block with no problems? Sorry if that seems like a dumb question, but big block fords are new to me! I'd like to put on the new SCJ ally heads from Ford Motorsports with revised valve angles and sizes.
Thanks for your help.
