I sent it to Dave Hughes, and he took it as far as they currently know how too. It flows a lot of air now. In fact, there is a back to back comparission between the 6 pack and a single 4 bbl intake on Hughes Dyno Page for the motor.

I initially had my Indy EZ's done by them as well, but after a valvetrain instability issue with hydraulic rollers; I ended up having Dwayne Porter rebuild the heads and remove some epoxy from the roof of the intake ports just behind the Max Wedge bump and set them up for a mechanical roller.

If I were to experiment with another Edelbrock 6 pack intake, I would buy one from Wilson with their full competition porting.

As it is now, I'm running a "350 CFM" center carb on my set-up. I do have a new "500 CFM" center carb sitting on my work bench to try some day, but I get amazingly good mileage and responsiveness with the "350 CFM" carb now. It already has plenty of power for what I use it for.


Thanks again for the reply! I will look up the 4bbl vs 6bbl Huges comparison if I can find it. Chances are I've seen it before, but now I have some perspective knowing it's yours. I have seen some using the 3x 500 CFM mech+accelerator pump carbs, and some say it's a big improvement and others not much difference.
