There were several production variables over the Hemi production years 1964-1971 so it is important to check your blocks for these variables and to record not just the casting date, but the other era specific stampings as well.

The casting date will be located behind the starter motor and will look like a typical date; i.e. 6 17 66 = June 17th, 1966.

We can start with just the casting dates to get things going, I'll post further related requests later.

Pictures of your dates would be awesome but just the typed numbers will be fine as well.

Here's one to kick it off 5-26-69 from a 1970 Superbird
