What engine do these head casting numbers belong with?

[gmcgone*gtx]

I recently acquired a 1967 GTX.

I've been checking out the numbers to find out what I really have.
I've got to some casting numbers that I can't quite figure out and I don't know how to find the information.

I'm sure there's someone here that does know the answer though....


Well, I do think it looks like this isn’t the original engine. That’s too bad but, it is what it is.
At least it seems to be a good running engine and that’s OK with me for now.


The fender tag has already been decoded.
VIN RS23L7702219

After checking the numbers this is what I've found.
I’ve highlighted the non-matching stuff in red.

Production Date:
6 – 5 - 67

Block Casting # 2536430

Engine Stamped Pad C 440
8 - 1 (1967)2

DS Ex Manifold 2806974
PS Ex Manifold 2806900

Intake Manifold 2806178

Transmission 261 – 4 6 - 5 (1967)

Radiator Brace 7760502219

Head casting #’s 2406518 or 2406516


The head numbers were the hardest ones for me to read the engine is pretty grimy at present; I’ll get to cleaning it up eventually.

I went back and re-checked the numbers three different times.

[FONT=&amp]The (cylinder) heads have casting numbers that are a mystery to me. They weren’t the #’s that they’re supposed to be according to the references that I’ve been using. And I don’t exactly know how to find out where they came from or any information about them.
[/FONT] All of the other numbers seem to be as they should to match the car. (other than the dates)

Thanks in advance for any info.

Here’s some information.....

Wow that was a fast track to info!

They're off a 1964 Max Wedge?

That's kind of crazy, I never would have thought they'd be from anything even close to that.

It is just a 67 440 with 516 closed chamber heads with 2.08"/1.60" valves. Sorry, no Max Wedge.

Looks like you are missing a digit in the VIN. Is it RS23L77102219?

Thanks Pops

I wasn't just commenting on them listed as being from a Max Wedge so much as, I'd be surprised if they were from a 1964 engine. But, I was already surprised at not only the engine being swapped out, but that they weren't from that engine either. This had been my brothers car since 1975 when I sold it to him. We lost him suddenly a few years ago. This car and several others were just sitting there and rusting away. So, we got a trailer and put in the miles to get it and a few others and brought them home. I'm learning there's a lot of unanswered questions. I thought I knew this one fairly well with it being in our family for so many years. There's so much I wish I could ask him......

One more thing, why is that casting number being linked to a 1964 Wedge engine anyway? What's up with that?
I had seen it there early on in my search but, I didn't believe it was right. I decided that I'd probably made a mistake in reading it and I needed to check the numbers again. There is another casting number that's almost the same at first glance and is a '67 440 casting number .

It's easy to get things mixed up when reading through columns of numbers. Especially if you're new to all of this.

Thanks guys.

If I recall the 518 number is Max Wedge but there is a very easy way to find out if they are really MW heads. Look at the intake manifold side of the head and in the center where the heat cross over normally is you should not see that horse shoe shaped cavity around the exhaust cross over port. The MW also has very tall intake ports that will not line up with the regular wedge. I bet you have the 516 as described above, which going by the book shouldn't be on a 67 440. The 67 440 HP got the 915 heads with the 1.74" EX valve.

Sorry, that is the number from the fender tag[FONT=&amp]. I've been staring at numbers for too long.

This is the VIN RS23L77225502[/FONT].

OK...let me see if I have this clear...you have a 67 GTX built at the STL plant with a VIN in the 225*** range giving it an SPD in early June of 67.
You have an engine with an assembly date C 440 8 1 indicating an engine assembled August 1 of 1966. (The C tells us it was for a 67 model year car. An engine assembly date of 801 67 would be for a D model, 1968, model year car.)

So it's theoretically possible that this engine was held back for 10 months then installed in this car but the likelihood of that happening is probably low.

The heads will have a casting date on them. Can you determine what the dates are?

It is likely you have a set of 516 heads which were standard 64-67 RB heads. Check the numbers on both heads to be sure.

The VIN is NOT on the '67 and earlier tags.

I've Read So Many Damn Numbers On This Thread That I'm Totally Confused! The 2406518 Heads Are 426 Max-Wedge Heads With The 2.08 Intakes And 1.88 Exhaust Valves! The Way You Know If You Have A Max-Wedge Block Are The Exhaust Valve Grooves Cut inside The Top Of The Cylinder Heads. But, The Head Is Stage III 1964 Max-Wedge Heads And The 1967 440 Heads Are Numbered 2780915 Heads Sport The 2.08 Intakes And 1.74 Exhaust Valves!

Thought I would lay this thing to rest.

After almost standing on my head and a number of contortions that I didn't think my body was capable of and an untold number of photos, I finally got a legible shot of the number.

The number is 2406516 not 2406518. As was said by 69Bee I believe.
On that one side it sure looked like ***518. But, after a while it's almost like looking at clouds, you either can see it or you can't.


Thanks for the info everyone.

i think the original engine should have the HP stamp on the pad and 915 heads
