Thunder AVS? Or Performer?

[71chevylowrider]

Alright You carb gusy & gals, I need some advice, I'm no carb tuner & I'm gettting tired of playing/tuning my Demon carb, I'm about ready to buy a new carb & I need some pro's cons, advice on what to look for, my truck is mildy midified with an isky cam roller rockers, RPM manifiold, decent camel hump heads, ceramic hooker headers, hei, blah blah blah, I just want to jump in my truck & fire it up & go have fun/enjoy it. Has anyone her tried those new Thunder AVS carbs from edelbrock? I had an edelbrock 1406 on it before & it worked fine, but now that I've experieced how much faster my truck is with the DEmon carb, I wouldn't mind going with something a little better.
