The 2200 uses an iron block and aluminum two-valve cylinder head. Output is {{cvt|120|hp|kW|0}} at 5000 [[revolutions per minute|rpm]] and {{cvt|140|lbft|Nm|0}} at 3600&nbsp;rpm. Displacement is {{cvt|2189|cc|L cuin|1|order=flip}} with an {{cvt|89x88|mm|in|2}} bore and stroke. 2200s were built at [[Tonawanda Engine|GM's Tonawanda engine plant]] in [[Buffalo, New York|Buffalo]]. This engine was replaced by the '''LN2''' in September 2002.<ref>{{cite web|url=http://archives.media.gm.com/division/powertrain/products/engine/truckengines/2003/truck_benefits/ln2.doc|title=Vortec 2200 2.2L L4 (LN2) Truck Engine, 2003 model year|format=doc|publisher=General Motors|accessdate=16 April 2014}}</ref> This engine did not commonly come with an EGR valve from 1998-2002 on the S-series trucks despite earlier versions using one. Instead a block off plate is on the back of the cylinder head. The camshaft on the 1998 model year uses a higher lift design. (0.288 inches intake and exhaust.) Meanwhile the 1999 and newer trucks use a lower lift camshaft. (0.263 inches intake and exhaust.) This was pulled from the Haynes automotive manual for the S series trucks.
