Carb Suggestions

Tell us about the engine. Everything you know.
What size carb is on there now? Cam specs would be very helpful. But if all you know is a part of grind number......

Generally speaking, a dual plane produces more low end torque. This will get you moving off the line quicker, street or strip. The RPM will also produce near equal hp to a single plane.

Carb wise, a 750cfm unit will provide enough. An electric choke is an excellent idea because it will give trouble free warm up, starting and driving.

You could put a vacuum gauge on it now and notice the vacuum level at high rpm. If it is greater than 1.5, a smaller carb can provide a few more top end hp. But it is a small gain. Sometimes the move to a larger carb will cause low speed driving problems. As well as a slight loss in throttle response. These issues maybe small but some people really want it “On the Money” and will go with a smaller carb.
