Hey experts, got a possible score for a friend on a 350/300 block and want to authenticate some numbering. Deck pad is: T0512HA, which Tonowanda, mid May, and I believe "HA" means originally with smog pump?
Engine casting # is: 8956618. I know there were a few casting #'s used for 69 350's, is this one correct for 350?
I'm trying to make sure that this is not a "DZ" motor, because even though that would be a good find, would not be correct for his '69 pace car (w/ small block).
Would you also identify for me exactly where the "DZ" or other codes are located on the oil filter boss? (pics welcomed)
