Hemi Engine Codes

[Scotto1]

Can anyone identify this engine code stamping on the block of this motor?

2468330-1

3-21-66

Thanks,

Hi!
Thanks for joining the forum.
Welcome aboard.

NOTE: There are more numbers you need to find.
1. PAN RAIL has numbers
2. The back of the block in the bellhousing area around by the starter is another stamping.
First off:
I'm not sure because Chrysler uses (used) a 10,000 day calendar but I'd say the easy one is the date code: 3-21-66, March-21-1966

The other engine stamping I believe is the CASTING number which I think in this case can be associated to the VIN of the car or sequential production number.
(I have a 70 Hemi but I'm not sure about the CASTING number 2468330-1)

Thanks...it looks like the numbers match. It must be a 66' 426. The motor is fully assembled and the block has been repaired from lower side breach. A new stamp on the front plate shows 1987. It was my understanding that the block was decked probably at that time.
