I'm the other way, I seem to always be able to make a Holley work and cant make heads or tails of an Edelbrock, of course I haven't bothered to learn since I can make a Holley work and frankly have so many of them sitting around. Holleys are very tuneable so I like that about them, important to make sure you have a good carb to start with, make sure the shafts aren't leaking and all the ports are clear. I really wish a Holley would just bolt up to the intake so I didn't have to change it over, if I'm changing intakes it's gonna be for the one I already have.
