no idea. everything i've ever seen says 78' or 79', but i believe that was last year of passenger car / pick up truck prodution and everything after that was NOS that was left over.
just went out and looked, block casting # is 3830930-440-6 so late production cast crank? i'll try to clean off the stamping boss on the front and get the head casting #'s tommorow and see what they say
