7-16-E and 12-10-K are date codes, Thats the month, day and year the part was cast. 7-16-E on a M part would be July 7 1959. 12-10-K is December 10 1941. The December casting probably wasn't installed on a production tractor until 1942. Maybe could be on a 41 calendar year model if you have one of the last tractors made in December but not likely even then. 6943-DJ is the block casting #, that # was mostly used for replacement blocks for M tractors.

Another indication of a replacement block is it may not have a engine serial # stamped in the block.
