ABSTRACT:
The instant invention is a rocker arm bridge support system for high performance engines. The bridge support system eliminates the compound geometry angular placement of valves with a rigid support structure using a common or segmented shaft for securing angular disposed rocker arms to accommodate the offset geometry. A bridge top secures the rocker arm shaft in a free floating manner by bolting of the bridge base directly to the cylinder head as well as the bridge top which is also bolted to the cylinder head by use of through apertures located in the bridge base. The invention includes the teaching of offset rocker arms mountable to the rocker arm shaft to accommodate the angular valve placement.
