So who in here races a 318?

Thanks, same thing with it overbored, but I'd still call it a 318 @ .030 though it isn't. Once a crank throw is changed, it's no longer a 318. The overbore is just an overbore for clean up purposes when building. The actual increase in displacement is small. Unlike a 3.31 stroke to a 3.58 or 3.79 or 4.00 increase.
