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

Depends on how much total HP you are looking for. You made need an aftermarket block. Most guys have gone with the cough, cough LS motors for boosted applications as they hold up so well.

I will need as much HP as i can get out of the combo in question. Not going LS or anything like that, despite much easier and cheaper.

Just wondering if there would be advantage to having BB heads and architecture vs a SM of equal displacement.
