    Yes, but you need to see to it the PVCR and the IFR is the same for the carb its going on. The idle screws adjust the same from one Holley to another. No more than 1.5 turns out, anymore than that something else is wrong or mis-matched.

    Metering blocks are different you should check the numbers of your carb to see what it should have on it.Small carbs have smaller metering block passages.For more info look here http://www.holley.com/data/TechServi...%20Listing.pdf
