Abstract
A multiple cylinder internal combustion engine having a camshaft-driven valvetrain with a camshaft disposed within an engine block includes at least two intake and/or exhaust valves with a pair of valves operated by a common camshaft lobe and a cam follower. The valvetrain may include independently operable mechanical or hydraulic lash adjusters. The cam follower contacts the common camshaft lobe and at least two pushrods with each pushrod having an associated single plane rocker arm which couples to a fulcrum mounted to the cylinder head to actuate the at least two valves.
