Well the trans has my vin info just like the block does.
I think I have bad info on how to date the block. The big casting number up on the side of the block are 9 0318642 and a guy was telling me it was a 68 block from that.
Casting number on a 383 block from '68 or '69 should be 2468130.
Here is what you are looking for - although this is from a 440. The casting date is shown above the casting number.
