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

That's shorter than a small block, that would be unreasonable lol, nearly 1 inch shorter.
The stroke you mentioned 3.100 with a 7.100 rod bbc journals and a 1.320 ch piston would work with a standard deck height block with .010 to deck square.
Fairly lightweight and rev to the moon, put some -1 or bigger heads with a tunnel ram, nitrous and 2 hair dryers.

You’d have a rod to stroke ratio of 2.29 and if you ran a car with over 270 advertised duration you’d never get the valve notched deep enough.

You could make the piston thicker at the valve pockets but you’re just making the piston heavier than it needs to be.

If it’s an unlimited induction class I’d shoot for a R/S ratio of 1.60-1.65.

If it’s an induction limited class then I’d be lookin at a R/S ratio around 1.80-1.85ish.

That’s IF I could pick the deck height.

That would be a 5.000-5.525 rod for unlimited induction and 5.600-5.75 rod for limited induction.

And whatever deck height I would need I set the pin height at a reasonable position so I don’t compromise ring seal.

My guess of a 9 inch deck may be a bit high for that length of connecting rod.
