I tried 3 carbs on my car (1 holley and 2 Q'jets... none which worked very well with 2 different intakes) before finally breaking down and buying a new 870 Street Avanger and a B4B intake... "Bolt it on and go" was 100% true in my case! I love the carb/intake combo and have no regrets. :TU:
i think demon is the only carb ready outta the box carb...of course very mild tune.....save ur money and buy a 850 speed demon:Smarty:
