4500 Mondello Posiflow


This all aluminum intake manifold for the 400-425-455 has an open plenum large runner and is recommended for competition use only. The improvements to this manifold include the use of 4 paravanes at the bottom of the plenum to direct the gas/air mixture through the runners in an even distribution pattern with minimum turbulence factor. Can be used with stock or HEI distributors (some minor modification may be required).
