I disagree with the notion that it “only” builds tq.
What I usually see, especially as the hp/ci goes up, is that when you start higher(more tq), you end higher(more hp).
My experience is that builds of equivalent effort, based around the same overall “theme”, will often end up making similar hp/ci.
Your saying that if I take the top end and camshaft off/out of a 560hp 416 and put it on/in a 323, it’s going to make the same power.
And my position is that those same parts that made 1.34hp/ci on the 416 are nowhere near exotic enough to make 1.73hp/ci on a 323.
