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?
Hard to say without knowing the specifics of the cam. However, I like the gear, converter, ported EQ heads, and the 5.9 magnum. I see a 7.70 or maybe even a tad quicker. Without being there in person, it's really hard to say.
