1. No advantage
2. No. Edelbrock carbs were built from the molds from Rochester purchased by Magneti Marelli . The 1901 and 1902 were made using the 1973 and 1974 molds the only difference is Edelbrock installed .050 air bleeds in the air horn
3. Yes
4. You can increase fuel flow but not air flow
5. Yes
6.No
7. Most use a professional builder
In a nut shell, you are at the mercy of the core as far as if you end up with a good carb or a not so good one. No builder can make a bad carb good. Fact is some carbs are just better than others and the only way to know is to run it down the track. A Quadrajet may show more HP on a dyno yet be slower on the track. I will tell you this, the fuel bowl is what makes or breaks the Q-Jet. Smart racers will take a number of bowls to the track and keep swapping them until they find the best one. Hope this helps.
