A little past the beginning stages of making a new intake manifold. Made to fit the stock chassis of a ChevyII, Camaro, Chevelle and the other GM stock chassis. Maybe not a G series van. Don't have one to test fit.
The runners are longer, cross section of port is smaller to raise the velocity. Also is made to fit up with a flat edged lump like a PES lump.
Water heated. No adaptor needed as it will be a direct bolt on for the Holley carb.
The first one is a 3D printed part. And it weighs only 3 lbs. Going to coat the inside, machine it to fit the carb and bolt to head and it will get real world tested on the 65 Chevelle wagon.
