I have a 1980 jeep CJ7 with a Holly off road carb. I use my jeep for running the dunes at Silver Lake, Hart MI. I do not like my holly off road carb because it does not perform well on the hills in the dunes. I want to change over to an Edelbrock and would like some input on what size carb to get. I am new at being a motor-head, so I am trying to learn as we go.
