What kind of carb do you have? Q-jets are famous for this problem. If you have a Q-jet, first check to see that there is a vaccume diaphram hooked up to the secondary air valve (the big flap over the secondaries). Not having this hooked up will allow the valve to open too quickly when you lay into it. If that is hooked up, there is a small screw on the passenger side of the carb at the top, and an allen screw underneath that locks the screw in place. It is kind of hard to see it. This adjusts the spring pressure on the valve, you may need to tighten it (Clockwise, I think). Let me know if this helps.
