ABSTRACT:
A multi-fuel internal combustion engine block, head and manifold assembly having a plurality of intake ports and exhaust ports communicating with a plurality of cylinders through one side of the assembly includes a low profile intake and exhaust manifold construction wherein separate, generally U-shaped intake and exhaust manifolds of generally elliptical cross-section communicate with the intake and exhaust ports, respectively, each of the manifolds including a planar face in contact with the face of the other manifold, the faces being of the same size and of a length corresponding to at least 50% of the total length of the intake manifold and of a width equal to at least 25% of the periphery of the intake manifold to facilitate operation on leaded gasoline, leadfree gasoline, or bottled gas.
