Question about "F" head 134 engine serial number.
Today in attempt to help identify the engine in my friend's 1948 JEEPSTER with body data tag of 4-63 77411, we found the engine to be an "F" head with serial number of: 4J384939, and casting number of: 807895.

I thought a 4-63 Jeepster had the "L" 134 Flat Head engine.
So we're thinking the "F" head engine has replaced the original flat head?

Any thoughts would be helpful.

Checking the early Jeepster manuals and even the 1954 Motor's Manual it is pretty clear the L134 was used thru 1949 and F134 came in 1950. The six banger units kept running the L-6 for another year or two.
