That’s a loaded question. It’s actually in answerable. It depends on ever last aspect of every last part of the engine & what size it is.
Steve Dulchich (sp?) wrote about this years back in MoPar muscle magazine. He took a (IIRC) .030 overbored 360 with a zero deck piston in it and ran gasket thicknesses to adjust the ratios.
Then dyno ran them.
Part of the compression ratio is to aid in efficiency by the cams running events lowering dynamic compression as the cam gets bigger.
Head flow testing between stock and various stages of being ported have been done as well.
You can watch engine masters for that. Again our hero if this thread, Steve Dulchich Ported a set of Edelbrock heads to run a comparison to the stock head on a blue print 408 stroker. The cam was a sizable street brawler ilk.
