Can you describe this "surge" a bit clearer? Like under WOT, or just accelerating w/positive boost, top of the rev band, lower down?
Is the carb in a box or are you using a hat? What's the fuel system? Pump/regulator type and psi setting? Size of lines, type fuel, filters?
Any possibility this is valve train related- as in float/lofting valves, too weak springs, etc.?
What is the ignition system?
