Engine Casting
I came across an engine block.
Looking for some input on what it is:
Casting# 3999289
Casting Date# K11 74
Other Casting # I see: GM 10 1
I also see CONV cast into it too.
There is no vin stamps or date stamps on the front pad.
What I think it is:
A Chevy 454 Block, that was cast on Nov 11 1074, for Conventional Fuel use.
Based on what I've provided, is there anything else that you can tell? Am I right in my decoding?

Yup. The casting number would be correct for a '73-'74 Corvette but obviously the date is too late. The same casting number was used across GM car and truck lines.
If there's a number after 'CONV' that indicates which conveyor line the block was cast on at the Tonawanda plant.
