I think it's again, personal experience, personal preference, and then outside influences, and then cost and availablity.

Much like the Camaro and Mustang, most people know of them, know that lots of people like them so they must be the car to get? Same with Holley.

I like the Q-jet (always like the underdog) and like the spread bore for both performance and for economy sake.

Then Edelbrock, easy to work with, and have always had good luck with them.

And then Holley... good over all carb, but I like what the others have to offer better.

For me it all comes down to cost. I can't afford to go out and buy the Q-jet I want, so I got the only thing I could find and afford, a 3310 Holley 750 that was almost new from a friend... it works, but I had to do a lot of tuning to get it set to run. I'm trading a few things to get an Edelbrock 750 soon, and will try that for a while... (right there with you Kel!) but probably will eventually get a Q-Jet...

I'm building another motor, so I'll need another carb at some point anyway! Lol...

But Like I said, I think as far as carbs go, you'll get as many opinions as the number of people you ask.

So go with what works for your needs like Jon mentioned, which sounds like a Q-Jet, Carter or an Edelbrock and not the Holley you are now running? Do some more homework and hunt for the best deals on what your comfortable with and you'll be happy!
