SB vs BB who wins?

Yep, but the 413 has a tiny bore, and more weight than a low deck. For relatively the same displacement, the 400 is a much better choice.
Now, if you have a 413 block you can bore .165 over.....?
413, better low end torque, sure, but rpm makes better torque and power on the big end.
Probably not across the board. That's a big cut.
