Don, I use to have the "hump" in my SS car and got rid of it by working on the Q-Jet. The basic problem is the Q-jet bowl. Its too small and makes the secondaries rich during high G's (launch). It takes a lot of detailed testing to solve this problem. Work on secondary rod shapes and hangers. If you don't have a Q-Jet disregard what I've said except for the "too rich" part.
