NovatoriusRex said: Hi guys, I was given a used Holley 4780 by my father over the weekend. From what I can find out, it's a street/strip 800CFM double pumper carb. Given that this thing doesn't have a choke or a kickdown setup on the throttle lever, I'm thinking this is mainly intended to be a strip carb.
