I have a 351 Cleveland out of a 1970 Mustang fastback. I am wanting to build it for street and strip use. Mostly strip! I am trying to find out whether I want to go with 4bbl heads or 2bbl heads. I want to get in the range of 400HP or a little more. Is there such thing as a dual carb intake for a 351C? Finally, does anyone one know anything about the "funnel web" intake for a Cleveland? (Intakes are my main concern right now) Thanks!
