Just a general question here.

Given a typical street/strip big block with 500-550 lb/ft of torque, would a lightweight flywheel be a little more streetable than say on a more high strung small block??

It is my understanding that a heavier flywheel helps launch by storing more energy than a lighter one. I'm also thinking that the hevier internals of a big block would help in rev matching and rpm hanging on upshits with a lighter flywheel.
