Let me clarify what I was trying to say. Both Edlebrock/Carter and Holleys are good carbs, I think it just depends on what you're comfortable with.
I don't like the idea of having to take off the air horn to adjust the floats on Eddys. And I don't like messing with multiple sets of metering rods in an attempt to find the right combination for the application. And I'm not real thrilled with having to bend the secondary linkage to get the secondaries to come in precisely when you want them to. And after you pull the air horn off the the accelerator pump has a bad habit of drying out causing it to flip up upon inserting it back into it's bore if you don't lubricate it.
Now on a Holley you can adjust the floats from outside, change springs if the secondaries are coming in too fast or slow, change accelerator pump cams to tailor the pump shot and change the pump shooters without ever opening up the carb. And since Holley now has metering valve blow out protection (there is an up grade for older models) they're almost bullet proof.
