Hi Res Pics of MP suffix with the Head Off
 

Figured I'd start a new thread to not hijack the other one any more https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Anyways, pulled the head and took some pics. Several of the "experts" seem to think it is a valid stamp, and the dates lines up, and the VIN stamp looks good as well.

looks good however the t and p have a ballbat looking effect I think that would be a stamp signature that couldn't be duplicated so it would either be correct or not but im in no way a expert

That effect is the result of the stamp being made while the gang-stamp holder was tilted slightly away from the block. Note that the entire stamping is deeper on the bottom than on the top. Not uncommon on real stampings.

It would be the only known Kansas-built COPO-Chevelle. Start looking for the rest of the car !

Judging by the amount of corrosion and pitting on the deck under the head gasket, I'd say it has not been decked and restamped. IF it was, I'd think the surface would be smoother. You could also measure the height of the head locating pin from the deck and compare to another block that is known to be original. I would think the machining process at Tonawanda would keep those hole depths within .002.

Our engine was only a few days away from this one. Other than a few swipes with emery cloth to show up the numbers, this is exactly as the engine came apart. [image]http://rides.webshots.com/photo/2814216980101686729RrFqdA[/image]

I have info on another unknown COPO-Chevelle with the engine dates just a few days away also.

Thanks Rainer. Never was much good on these computers. Give me hand tools and it is a little different. https://www.yenko.net/ubbthreads/imag...lins/smile.gif
