Thanks for this info.
When were these numbers put on the engine? I'm assuming the casting numbers were in the mold when the iron was cast which would mean the L140 was cast December 14 1960. The distributor boss was then the next day? Would that have been stamped when the engine was assembled? If so, then they didn't waste any time on this one.
What about the numbers on the head B41 848 and right below the 848 are the numbers 850?
