I will be using a carter 600cfm for my carb. I am making a manifold which will be the similar to the clifford one, only with a larger plenum. I will also be making an adaptor for he carb... basically a 90 degree elbow for the carb to sit on top of.

Hank, I will look at the link you posted when I get a few more minutes... I am supposed to be working now.
