ABSTRACT:
An overhead cam internal combustion engine having a slanted head design which permits the camshaft assembly comprising a camshaft, rocker arms and valve assemblies to be pre-assembled to the head and valve lash to be set off of the main engine assembly line. The slanted head design allows the chain sprocket and timing chain for driving the camshaft to be installed thereon after the head has been assembled to the engine block, accommodating the easy installation of the timing chain. L-shaped rocker arms, mounted on a single shaft, follow a single lobe overhead camshaft. Each rocker arm actuates a valve located on the side of the camshaft opposite that which it follows.
