The Dual Port 360 can best be described as two manifolds in one. The entire manifold is divided from the base of the carburetor to the head flange. The percentage is, of course, a closely guarded secret on this patented design that varies from engine to engine. The result is low end torque and economy of a 180 degree intake with the performance of a true 360 degree manifold.

I purchased an older (pat. pend.) version of this manifold and the hole for the distributor is a 1/4" too large in diameter for the HEI. Will I have the same problem with this newer manifold?

The distributor hole on small and big block Chevy engines does not fit tight. As long as the flange of the distributor will catch on the surface and seal up then it will work fine. There is no issues with the distributor hole size in this manifold.
