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.
