Ported Edelbrock versus W2 out of the box !
That certainly doesn’t seem to be the direction things are going.
If that was really the hot ticket for everything ...... I wonder why they’d start out with chambers as small as:
Vizard has some interesting results in his SBC porting book relating to this.
Even though the “open” chamber SBC heads(that have the same port configuration) flow more than the equivalent “closed” chamber head, and even after equalizing the chamber volume so the CR remains the same for the test, the closed chamber heads made more power.
