You first have to determine the CASTING date of the block which is located on the side of the block. It will be obvious such as 1-15-70 as in Jan. 1, 1970 Then the top pad numbers will make sense. The T can mean eith the model number year OR truck depending on the year of the block.

1969 model year was E 1970 model year was F on the top pad and it went up from there alfabetically but some letters were skipped because they could be mistaken for numbers.

Yes, the casting date will narrow it down but the stamp pad info you put up indicates late model engines. I'd say mid to late 70's. The 4T could mean 1974 and if the block is cast in 73 then that's it.

Ah, an 8-11-78 casting date! Proof that there were 1979 vehicles that came out with a big block! I've heard so many say that didn't happen when I've seen a few back in the day...one being a Magnum.
