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

True but the R/S ratio is still too high.

I was giving examples of how I’d build it. And that’s the math that comes out.

Which BTW is pretty close to the deck heights in Pro Stock. IIRC they are in the 9.200 range with about a 3.6xx stroke.
That's just a little over a stock 400 lol
