New best last night.. still having problems getting enough fuel through this carburetor. The largest jet that I have is a 164. I know it wasn't the right thing to do but changed to a tiny high-speed air bleed. Trying to accommodate the fuel needs of the motor. The carburetor was not designed for the application it's being used. despite afr's in the high 13s and low 14s.. still managed to rip off a pair of low forties. These small block Mopars are amazing
