If the block has no numbers stamped anywhere would it be considered a ‘warrenty’ block?

I'm no expert, but I thought that they didn't even stamp a VIN number in the block until the 68 model year.

They were still using 66 casting date blocks into 68, or at least that's what I've been told.

66 and 67 model year cars wouldn't have the VIN stamped into the block, just machining dates I believe.

Just guessing here, but if there are no numbers on the top machined pad. Im thinking over the counter block . Or what some call a warranty block

And , Yes there are no VIN numbers stamped in till 1968 vehicles

I agree with gtx6970, it's an over the counter or service block. All the warranty engines I've ever seen have been a minimum of a short block and have the warranty tag riveted over one of the casting plug holes. This is NOT a Hemi block but it would be similar,

Didn't they put numbers around where the bellhousing mates to the block on the topside in some cases?

I believe you are referring to the early '68 VIN location.

Could someone have milled the top China rail and removed original numbers?

Unintentionally or intentionally?

I mean people do all kinds of crazy stuff to Hemi blocks.

This it ???

Possible. If it is a '66 casting and there is no VIN stamped on the top rear, then I would think had the engine been in a car it would had to have been either a '66 or '67. If so the pan rail should have the build date stamped on it. When the OP said there were no numbers "anywhere" I took this to mean the pain rail was not stamped also. But that is an assumption on my part.

After cleaning the pad found these. Where are those numbers on your block?

Pan rail "ear", rear, starter side. The "WT" is for water test, the "F", don't have a clue.

Thanks, only this. As you can see ear was broke off at one time, I’ll cut and weld back correct.

The WT stamp on the top pad is more common on blocks used in cars after 1967. Blocks from 1966 year model cars were stamped BH 426 on the top pad, Blocks used in 67 year model cars stamped CH426. Beginning is 1968 the top pad was mostly only stamped with the WT and that seemed to continue through the end of production. That being said what is the casting date of the block? With no hemi blocks cast in 67. Some late 66 casting were used in early build 66 cars. From my knowledge the first run of new hemi casting would be 1-15-68 blocks so anything built before most likely got a 66 casting block.
Look on the rear of the bell housing flange as was mention for a 68 partial vin, it will be close to the oil pressure sending unit location. It could also be an over the counter block too, with no Julian date code stamp for the machining date. Any more pictures of the block would be great.

1/27/66 date on block. No numbers on the bell housing lip like my 68 block has. Went over the whole thing with a magnifying glass. I’ve had warranty blocks it has no rivet hole for the blue tag. So I’m guessing an over the counter block. Bad part it’ll have 2 sleeves and punched .060

I would question that.

I guess what I was really saying is the WT stamp by itself with no other stamping to show the year cars it was used. Both the blocks you show do have the WT but also have the BH426 and CH426 so 66 and a 67 block with the WT stamp. After those, the WT is all that is found on the top pad so nothing to specify the year car it was used in. Hopefully that better clarifies what I was saying.

That WT does not look original to me. There were plenty of 66 block over the counter for racing in that time frame. I also have seen several BH 426 block with WT stamps. Random placement on pad, not neat and in line like the picture. But who knows for sure.

Found the rivot that held the warranty tag

On the bottom of the pan rail it is clean with no Machining Number or Assembly Number or year Identification Letter, i would be looking for the rivit or the rivit hole to see if it was a Warrenty Block. No Year Identification on the top pad also make one thing to look for the rivit or rivit hole.
