Put it over the aircleaner stud on either carb to block off all airflow and test drive---then switch it to the other one and drive it--leave it on which ever carb that makes that little 302 run best with 450cfm carb. When you find which carb runs best , glue the dvd to the garage wall!!!!
If you want the dual quad look----block off the seconaries of both carbs, or if creative, just block one and run linkage so it acts like 3 x 2s.
