the info between the first letter F
and the last letter H,
is the production date, month and year.

What is the raised block casting number.
Something like 3837004 or 3836233.


I have seen that on other engines, like F57123H

But this Code is the letter F the letters II then 4 then the letter H

that is what was confusing me. no year date, and the only number is 4 anywhere on serial number pad.

I will get the casting number, the engine is in the barn, which is about 17 miles from where I am now.
