The good news is a big cube SB2 motor does not need a blower to make 700HP by accident!

You beat me to it Frank-- I'm currently trying to talk a friend/"customer" out of trying to turbo a used SB2.2 he bought complete from Childress. Just ain't gonna happen without making lots of sacrifices in the piston department like you said, not to mention you end up killing the quench in the chambers with the HUGE dish needed to get the CR down even into the 9's!
You are right though, don't need much breathing help on a SB2 to make good power numbers.
