Finally 8.0’s
Irwindale Raceway California is 370.8’ above sea level, my car with me in it weighs 3650. I did not know how to post without the voting option. Do you think a double pumper will get me into the sevens like it is? This is the carburetor I have on it. A Holley HP 750 vacuum secondary. I’m at the end of what I know to get more out of my combination, any Suggestions?
