Carb Suggestions

My experiences with 440s has always been, if they have been modified, they need more than a 750. Closer to stock? 750 is great once dialed in. Add headers, cam, intake?...a bigger carb, once properly setup will kick it's butt. Tuned right, they can have every bit the off-idle response but deliver more pull from the midrange on up. Be honest to yourself about your goals with it and go from there..
