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

Those are all unavailable options though. There is another rod length that is a tad shorter which would make more p/v and since he wants boost that might make it better. I'm not sure if a turbo cam would need to have that much duration
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.
