The Vortec 2200 (RPO codes L43 and LN2) is a straight-4 truck engine. It is entirely different from the Ecotec 2.2 car engine, based instead on the OHVIn automotive engineering, an Overhead Valve or OHV piston engine is one with pushrod-actuated poppet valves perpendicular to the pistons. This contrasts with previous designs, including side valves and sleeve valves.

It is designed for longitudinalThe term, longitudinal means "front-to-back" or "top-to-bottom" as opposed to transverse which means "side-to-side". In automotive engineering, the term, 'longitudinal' refers to an engine in which the crankshaft is oriented along the long axis of the veh mounting.
The main change from the L43 to the LN2 was its electronic control module. It also uses air injection to improve emmissions and loses the "flex fuel" ethanol compatability.
The 2200 uses an iron block and aluminum 2-valve pushrod cylinder head. Output is 120 hp (89 kW) and 140 ft.lbf (190 Nm). Displacement is 2.2 L (2189 cc) with an 89 mm bore and 88.00 mm stroke. 2200s are built in Tonawanda, New York.
