It isn't a K engine. That number is a '75 F0 engine.

Thank you soo much. I was nearly about to lose my macaroni trying to figure it out. 3 different graphs for engine codes and I still couldn't figure it out. God bless you

F0 engines are tough to come by.

I spent 11 months trying to find one before I eventually did.
