Is there a list anywhere of known casting dates for Hemi blocks? Have a block that the year is ground down, month and day are still there though.

Is there any truth to what a friend and '70 Hemi Cuda owner once told me that Hemi blocks were "aged" in outdoor storage for months after casting and before engine assembly?

Thanks for the responses, I'm thinking the 5/10/69 looks pretty likely, I was thinking it might be a 5/19, but it could be either a 9 or a 0. It an NOS over the counter block, so no numbers I can see anywhere. Only the normal WT on the pad

the closest cast 1/15/68 to assembled 3/12/68 dates I have any info on are ~2-months, but most are much longer - that may be due to size of batches & rate at which they were used work was it intentional?? shruggy

the '66 & 1/68 blocks don't have the raised pad for the VIN stamp

Add the date 4/15/68, the first of them was installed on the first Hemi roadrunner, built on 7/28, Lynch road plant.

I think I remember actually seeing a photo of raw just cast Hemi blocks rusting and stacked outside what may have been the casting foundry?? Seems to make some sense to have the cast iron age at least a short time.

I will check again, but I have a 1/15/68 block assembled 24May68 and it has the raised pad for a VIN but it is blank. Vin is in the normal spot for a 68 hemi motor.
