Proform? Quick Fuel?

What should I do and why?

I asked about them awhile back. If you look down the list a little I never got an answer. hopefully this time we will.

I purchased my carb from Pro Systems after many recommendations on pro-touring.com and camaros.net . They have an online form where you describe your engine/drivetrain/etc and you'll get a response back from Patrick, the carb guru. I haven't fired up my engine yet so I can't say anything about its performance yet....but if you're starting from scratch and and you want a warm fuzzy feeling from someone who really knows carbs, at least throw your hook out to them. I myself am completely a carburetor newbie, and in my conversations with them I'm sure it showed. However, they treated me well and were very helpful discussing my options. Patrick didn't even try to sell me up on options that I thought I wanted/needed, like annular boosters.

im thinking about trying one of the new ultra street avenger carbs, i'm running a 355,(roughly 430-440 hp) t56 6speed, 411 rear. i now have a 750 hp double pump on it but its like a milk jug on top of the engine just dumpin in the fuel....good performance , but i am thinking i can get as good or close with a vac secondary and alot better mpg.....

I have run several BG's, Holley HP's and one Quick Fuel P series. I like my Quick Fuel the best off all. It was the first carb that let my TA idle in gear at 950 rpm. I have a big cam. First time I don't have to crank the idle up to 1500. I set it at 1050 and it drops down to 950 and idles nice in gear.
