I had a Proform 750 DP on my 340 for a few years. It ran fine - hit really hard when accelerating.

I currently have a Edelbrock on the car because I realized that I never took the car to the track, so having a carb without a choke and 50cc accelerator pumps was probably overkill.

I might put it back on though - the E-brock just doesnt give me the kick in the pants that the Proform/Holley did.
