Default Re: 1938 "B" diamond engine

Duffy 1,

The diamond block A, in addition to the hard seats in the exhaust valves, may also have a B camshaft. If you have the pan off you can look to see if the camshaft has a round lobe at the front; this lobe was for driving the fuel pump on the B and C engines. Often times these blocks are engine number stamped starting with RF**** or LB****; RF= Richmond Ford and LB = Long Beach Ford.
