Guys: I will try to help forum members on a limited basis with intake manifolds, but I am trying to keep it at a minimum. I still have not gotten to a couple of my own projects. I have been helping a couple of my old customers with really neat combinations, and it has been fun.(270-280cfm through a 1.94 intake valve.) If you are not in a hurry, then e-mail me with your need, and I will see what is possible. Joe-JDC.
