Probably a Dumb 318 Question

Hey there folks, I was just wondering and I’m sure no one has a direct answer but I’m thinking… most people say that there is not much potential in the 318 but I remembered the ford coyote (5.0) is actually quite a small engine yet this engine outputs 460hp 420tq with just a 3.63 bore 3.65 stroke. 12:1 comp ratio on pump gas!!! 55cc head chambers cam around .550 lift. So my question is, is this doable to a 318 if not why? Is it the aftermarket head and piston support holding you back?
Thanks in advance
