    Comments about Proform Carburetor Main Body for Holley 750 Cfm, Vacuum Secondary Carb:

    It took less than 30 minutes to change out the main body in my holley 750. I'm using the carb on a fairly built 396 that's good for a 12.85 quarter mile in a 65 vette. The difference was impressive. No noticeable degradation down low, very noticeable improvement on the top end. I haven't taken the car back to the strip, but I'd say that the Proform main body is a very cost effective way to pick up horsepower, assuming that your engine could benefit from more air-fuel. It's a whole lot cheaper than a Holley HP.

    • Q:

      does the holley 750 proform work with vacuum disk brakes? And Edelbrock intake?

        I'm happy to help, Fred! This ProForm Carburetor Main Body for Holley 750 Cfm, Vacuum Secondary Carb (Part No. 67101C) is engineered to fit a Holley 4160 series 750 CFM carburetor (Part No. 3310). Typically the vacuum for your brake booster is connected to the intake manifold, so the main body replacement should not affect your booster. Installation instructions for the main body are available here:

        Instructions for a Holley 3310 carburetor are available here:

        Without knowing the intake manifold you've chosen, it's difficult to predict if the carburetor will work well with it. If you could please provide the part number of the intake manifold you have in mind, we can provide more details. Edelbrock typically provides carburetor recommendations with their intake manifolds. We can also provide additional product recommendations with if we have an idea of the intended purpose of the vehicle. It looks as though you will require an Edelbrock Performer RPM Series intake manifold. These are best utilized for 1500-6500 RPM engine speeds and may not work well for a daily driver.
