What do the different numbers on the pad by the distributor mean? No I do not have a pic of it, I just wrestled it around for an hour trying to find every number I could on it. I know it says B426. Casting date is 1-17-66, day shift about 6:25
Any info and examples would be helpful. Thanks.

Edited to make pics easier to read.

B is the model year 1966

What other numbers are stamped on the pad?

 

[Fran Blacker]

Any maltese cross or diamond stamp?

 

[Nxcoupe]

Maltese cross. Looks like a date code but there are three numbers stamped, one on the left and one in the center and one on the right. Just want to know if any are build date. Nothing stamped on the bottom oil pan rail.

I have a 440 with Maltese cross, and iirc that means the crank was turned by the factory and the bearings are undersized

 

[Fran Blacker]

The 1-17-66 is the engine assembly dare. Maltese cross is about undersized crank, .001 U/S could one or more journals. Look for stamp on #3 outside counter weight. Measure crank to be sure. To the right of the 5 is M for main to left of R rods 5678. 5 main and 5678 rods U/Sed.

Isn't that the casting date on the side of the block? Yes, that's what the maltese cross means, but I don't think I have the original crank. However, it still has main bearings in it which I'm going to pull out soon and can post up the part numbers if they are still legible.

Anyone know what the numbers on tge pad mean besides the B426?

 

[turbine68rt]

Is the 1-17-66 stamped on the pad near the distributor or on the side of the block? If it's on the top pad @Fran Blacker is correct.

This is mine. April 20 assembly date. I don't know or I forget what the sideways T means (see the forget thread). The cross has already been commented on.

This is what I wrote. It is cast on the side of the block. I took a pic of the side of the block to post it but it disappeared from my phone. I will get another pic and post it here. My back quit hurting so I'll flip it back around and take a pic of the pad, but I believe the post above covered it for me.

Thank you! Exactly what I wanted to know. What is the second 20 for? I searched and found that thread on the 65 race hemi block and it had numbers stamped on the bottom oil pan rail ear. Mine does not have that so I was confused. I will get pics of everything and post them here dor posterity and search engines.

Post edited to include pics for posterity.

I don't know what the other 20 is. It might be an indication that it's the 20th engine assembled that day. Maybe some of the other Hemi guys know.

There is a “W” under the assembly date and before the “T” and together I assume it means water test was performed.

 

[Dragon Slayer]

WT is water test.

 

[gtx6970]

BH426 is 1966 hemi
WT is water tested .

Maltese cross is undersize mains,,,,,, I think ?????

And best i remember the 3 is 3rd shift , 2-29 is Feb 29th assy date

Im going off of memory so dont shoot me if Im wrong , cause it aint what it used to be

 

[Nxcoupe]

WT is water test.

I think he was talking about mine? It has WT under the other stamps.

I believe the 3 and 2 are March 2, and the 28 is the 28th engine that day? I mean if you look at the other 66 pad above, he has 4 20 20, which would be 20th month 20th day, otherwise I would have agreed. I think the first 2 are the month and day as that other thread linked here alludes to, however no mention is made of what the far right number means. I would ASSume, that means the number of engines built that day.
Anyone know for sure on that?
