What would you build if limited to 372ci - with boost as an option

I am not sure how far the crank can be turned. The 383 is a steel crank, 10:1 motor. 383 con rod journal size is 2.374. Could it be offset ground big block chevy rods used?
I think people have ground the other way to 3.55" so that be 3.21" might be possible.
