holley or edelbrock?

i agree with either the eddy 600(performer#1406) or the holley 670 street avenger. the eddy 650 is a avs design(spring operated rear air door), so no need to add a variable you don't need to know about right now.

the eddy booklet walks you thru it and tells you which rod/jet changes to go to if needed and how to adjust the floats.

73dodge, I'm going to have to disagree with redfastback, but he does make sense about complicating things. But I do not think an adjustable airdoor will add to problems.

While the air door can be tuned and add's one more thing to a list, it should be left alone until the primarys are tuned and that is where the most power comes from. Then you can move onto tuning the secondarys. After that, you can tune the air doors opening rate. Best to do that at a drag strip where you can see the times rise and fall.

Have no fear. Do one change at a time. It isn't hard, just consumes time. Take your time. You'll be fine.
