Missed on this combo?

Well...come on, man! I got's 'ta know.....How does it look? Now that I went back out there, the Edelbrock seem a bit flatter. Not much, though. The overall port seems way smoother transition-wise, and not nearly as "bulbous" as the Edelbrock.

I tell you, I'm scared shitless to bolt these on. I had to sell stuff to buy them and boy, they better make a difference.

Long as I don't bolt them on, I can return them if I don't like what I see. First they will need milled. Supposed to be 70cc chambers. I need 68. I will cc them tomorrow. Anyone have an idea how much to mill for 2 cc's?

You send then back i'm going to Hurt you!:poke::D

the smoother the air can travel the more HP potential it has.
The biggest challenge is to keep the air attached to the SS! if it jumps of the SS it crashes into the valve(turbulence) and turbulence kills performance The smoother, rounder that it is and still have a large enough Cross Sectional area to keep the air speed within reason wins!

Put both then head back on the flow bench and only flow them at .600 lift. You will hear which one is the winner! (Hint turbulence is more NOisE)

This is only my opinion/guess
But they had too much air speed and it was jumping off the SS. So to slow down air speed you make it larger in that area. theY must not have been able to widen it or take more out of the roof........so they cut into the ss.
Slowed air speed down but now you have a smaller (less round) SS. The flow bench### my not have caught the problem......but you're running eng DID. :)
