Wow! Is one of the venturi sizes BIGGER than the throttle bore? I looked at some pictures of this carb. Looks like a triple Venturi metering rod type carb. The stromburg 97 is rated at about 155 CFM, that puts you a little lower maybe 130-140 or so. If you get the same crisp response that I get with my Dual Jet driving the car will be a blast. IMHO the triple Venturi makes a big difference in part throttle driveability even if a little CFM is sacrificed. Have you considered bigger air cleaners for more airflow? Jay
