GVWR)The LC9-5.3L V8 E-ROD Kit is a complete engine and emission control package designed to change engines from all 1995 and older passenger cars and trucks with up to 6500 lbs. test weight (7200 lbs. GVWR). The kit is derived from a federally certified 2012 model year General Motors truck engine (test group CGMXT05.3373) but with modifications to the original emission control module (ECM) calibration, exhaust system, evaporative system, and air intake system. The main components of the kit with their corresponding part numbers are listed in Attachment A. Installation of the LC9-5.3L V8 E-ROD Kit requires complete removal of the stock pre-1996 model year engine, including its exhaust and evaporative emission control system. The stock fuel tank, hoses and fuel pump are retained but need to be reconfigured to meet the installation requirements of the LC9-5.3L V8 E-ROD Kit. The kit is equipped with a fully functioning on-board diagnostic II (OBD II) system except for the diagnostics related to the evaporative system and transmission. The stock vehicle check engine light is retained or needs to be added for older vehicles that were not originally equipped with a check engine light in the dashboard. The exhaust system, catalytic converters and oxygen sensors must be installed in the location/orientation as prescribed in the installation instructions provided with the kit.
