Does anyone know if there is a difference in specifications for the pre-and post-war 245's? I have three of the 245's, all, it appears, post-war, but I don't have any specs for anything past my '40.

Thanks!

T've only ever had prewar 245s (I still have one of the engines, mostly rebuilt) but in the ‘60 when working on them, my Motor’s Manual was 1956 which went back only to 1946. The only real difference I noticed was that the postwar had larger rod bolts so had a different torque specification. I'm not sure but I seem to recall that the design of the valve keepers also changed postwar.

Thanks--that's helpful.
