340 engine ?

With those heads you can run a smaller cam, I look for something around [email protected]. The RPM is a great intake but if you want something different look at Offenhauser, I have the high rise equal flow single plane which has a divider for low speeds and its good to 6500 rpm. I had a performer before that and my idle is better now that before with a dual plane, its a real good single plane intake for the street. I have a Holley 750 dp so I should know if its good on the street. The newer torker and other single planes are for racing. Hey if you are in Germary get a German intake!
