Holley vs. Eddy

As long as both carbs are the same, square or spread bore, it will bolt on. Will need that mopar throttle arm to hook up auto trans kickdown if using one. Might need to change out power valve depending on which one is in the carb, and possibly rejet if running rich or lean. On the edelbrock carb, jet change and/or metering rods and springs will get your current carb leaned out.
