How would I go about changing my cc distributer to a vaccume advance one, Since I think thats what needs to be done when I change my carb from qjet to another type, dont know what type. Any input whould be very appreciated.

 

Check out the Carb Fourm. Why do you want to change out your CC carb? Your Rochester carb can flow enough air to support a 400 ci engine with a simple mod. It should give you great throttle responce, and with correctly functioning computer feedback, good gas mileage.
