My main bearings have a B on them???
My '72 455 main bearings have a 'B' on them. The factory service manual says that means they are 0.0010" bearings. I assume this means undersize? Was that on the diameter or the radius? Did the factory just use the different sizes to compensate for slight differnces in crank main journal machining diameters, or does that mean it was rebuilt at some point? Thanks. Tom
