Now tinkerbell has mentioned that the b18b's internals aren't stronger.........but is there any hard evidence to support this (I recall you made a good post re the head of the b18c and its strenths over the b18b), but what about the bottom end?
ok, did you know that the B18B only uses 8mm rod bolts and the B18C uses 9mm rod bolts?

did you also know that the B18C has a bearing cap bridge and the B18B doesnt.
