I've seen A LOT of posts about making HP with a 318-So why is it so ???

A 3.55 would wake it up pretty good.

It would and I may go with them or even deeper, I don't drive on the highway much. For Now I'm keeping the 2.96 plan on swapping a dual plane and a 262HR-12 cam or similar got most of the lift my cam has but lot less duration and wider lobe separation, then I'll decide what gear if any I want.
