What makes the newer 3.0 vulcans have 10 more HP then the older ones?

It's the Upper Intake Manifold. And that's on the 96 and up.

Doesn't the Gen 4 Vulcan have like 10 more HP than the Gen 3? I thought it went:

Gen 1 & 2 - 140 HP
Gen 3 - 145 HP
Gen 4 - 155 HP

 

[Adam B.]

Yeah, those are the numbers. But I've read the the gen 1/2 get 10-15 hp from a gen3 intake
