    What is correct CFM for stock 63-65 401 nailhead dual quad set up? I'm assuming they were all the same.

    I am the first to say that I am not a nailhead expert. But to the best of my belief a 401 duel quad engine was never a factory assembly line option. I recall all Super Wildcat engines were 425 cid.
