Folks, We have a C1BA flathead v8 in our '48 M47 pickup which has obviously been re-powered with a '51 flathead v8. My question is what is the likely hood of this later engine being a 255 cui engine and not a 239? I would prefer not to drop the sump or remove a cylinder head to measure the stroke purely for the reason to not disturb a perfectly running engine with 110 - 115 psi compression.
C1BA heads came on Canadian 1BA 1951 Ford 239 flathead engines. Mercury heads were marked 8CM or 1CM or EAC, and if Canadian, the ID would be preceded by the letter C, as in your example on your heads.
Because it is made by Mercury is the only reason. The engine block has C1BA moulded in to the top of the bell housing and I am curious if the later Mercury flathead engines were produced with 255 cui as standard?
Only the 1952 M-5 and M-6 Mercury Trucks were available with a 255 engine, all others with flat-V8's were 239's. Mercury Cars all had the 255's, from '49 - '54 (in Canada).

So is it possible that we may have a Mercury car flathead in our '48 pickup because it certainly doesn't have the original engine?
