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

Thanks, just remember this is for Bonneville. 5 miles of getting to speed, little traction, heavy car, skinny tires, etc. Speed markers are at 2.25, 3, 4, and 5 mile marks. Displacement, fuel type and car modifications dictate classes. I am ok with boost on my 383, but record looks better for less than 372ci.

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.
