Bullsh*t, It's well documented that quadrajets are awesome if you take the time to read the instructions and tune them right... Infact they are one of the most tunable carbs ever. I get 18MPG on my 450HP magnum on the freeway with one. 3 speed 3.73 gears. Pushes me back in the seat when I want secondaries and purrs like fuel injection when I cruise. $70 including rebuild well spent. My QJ Sells it's self.
