I have a 79 Bronco with rebuilt 400m, msd electronic advance, and it has a cam but im not sure the size. I just bought a 770 holley 4 barrel truck avenger carb and everything works fine except it bogs and stalls if I punch it at all. I have a new fuel pump, and high flow filter. Idle and jets are set right and if I start by feathering it and build up speed it does fine. Could it be to big of cfm of maybe I need larger fuel hard lines to tank?
