I was "318", when 318 wasn't cool......

IMO if it's over bored it should be noted.

It DOES change the displacement.

Most people are too lazy to do the math.

I have heard a few folks say things like "now it's 322".

I guess we can say the jury is out on if a .010 or .030 over is still a 318.

Again, I suggest an asterisk.

...but a 390 is most clearly NOT a 318, despite what the block casting says.
