You have no clue. Super Stock and Stock class cars must run OEM carbs. One of my friends raced Super Stock. 10 seconds flat with a low compression Chevy 350 and a Quadra-Jet. His friend raced a Stock class 71 340 Duster. He was so fast, Chrysler was giving him parts to try. Raced using a Thermo-quad. After hanging around those guys I figured who was BSing me. Never looked back. Sold all my Holleys and the pile of "tuning" parts. Wow, better running cars, better mpg, and set and forget. Stopped having to "tune my stupid Junk Holley and rebuild it all the time. Now I just enjoy my car. Believe what you want, just don't try to sell it to me. I've seen the light! I've also loaned carbs to friends who thought Holley was "THE" carb, and none of them wanted give my carb back.
