my basic understanding of it is that port cross section with directly effect port velocity and it will gernally dictate that a certain rpm is going to be most efficient and you can work to widen the torque curve with good matching of components. I know the cam duration / overlap and LSA and centerline can have an effect as well as intake manifold.
I really do wish I knew the cross section of the strip dominator and Trickflow 190s to do some of the math on my 408.
In Andy Fs book on big block strokers I can't recall exactly but he said your peak rpm will be about 5500 because the torque peak would be around 4k I think he said unless you used raised port heads when building a 500 cubic inch stroker.
