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

Yup. And were I building your engine I’d be worried about piston length.

Can you ballpark an appropriate rpm the cars in your class run?

Since you want to reset a record I’m assuming you want to be competitive so that’s why I was explaining why tall decks and short strokes cause issues you might not have thought of.

So, Turk,, would you run a longer rod and shorter piston, or whatever height of piston that works with the short (or, shorter) rod?
A .030 over 383 block with a 3.23 stroke crank,and a 6.800 bbc rod, needs somewhere around a 1.5" ch piston, depending on the deck height of the block.
371.7 cubic inches.
