The original Panifold is back!! This is an intake manifold that has been engineered to improve the flow and atomization of the air / fuel mixture for 74" Harley Big twins. The improved flow characteristics are attributed to the radius corners and "Y" shape direction routing inside the Panifold. The result is an improvement of 20% increase in flow over stock!!! This is a lot in the intake world. Bench flow testing and overall design thumbs up by Paul Hasselgren of Hasselgren Engineering. Building serious racing engines for nearly 40 years Paul knows how to make power! The Panifold fits 74" 1955 to 1965 Panheads (with o-ring heads). Any 74" Panhead or knucklehead that uses the plumber style intake seal can be upgraded to the better o-ring type seal with adapter nipples installed. The steel nipples are available from this web store. The mounting flange is the standard two hole diamond fitting any S&S L, B or E carburetors as well as many others using the same mounting pattern or adapter flanges for CV carbs. We've recently updated the design adding some clamp stops to keep your clamps form moving around and causing intake leaks.
