The 6.2L diesel was a high-MPG alternative to the V8 gasoline engine lineup available, at a time when the market was focused more on mileage than raw power.<br /><br /><span style="font-weight: bold;">Specifications</span><br /><ul><li>Engine RPO Codes: LH6 ('C' series, with EGR) and LL4 ('J' series)</li><li>Displacement: 6.2L / 379 cu in</li><li>Bore x Stroke: 3.98 in × 3.80 in (101 mm × 97 mm)</li><li>Block / Head: Cast iron / Cast iron</li><li>Aspiration: Natural</li><li>Valvetrain: OHV 2-V</li><li>Compression: 21.5:1</li><li>Injection: Indirect</li><li>Horsepower / Torque (at start): 130 hp (97 kW) @ 3,600 rpm / 240 lb·ft (325 N·m) @ 2,000 rpm</li><li>Horsepower / Torque (at final): 143 hp (107 kW) @ 3,600 rpm / 257 lb·ft (348 N·m) @ 2,000 rpm</li><li>Max RPMs: 3,600</li><li>Idle RPMs: 650 + or - 25</li></ul><br /><span style="font-weight: bold;font-size:130%;" >6.5 L</span><br /><br /><span style="font-weight: bold;">History</span><br />The 6.5 L (395 cu in) version was introduced in 1992 to replace the 6.2. Most 6.5s are equipped with a turbocharger for added power and fuel milage. This engine was never meant to be a power and torque competitor with Ford/International and Dodge/Cummins, but rather a simply designed workhorse engine that made good power and achieved for the time good fuel economy. The Duramax 6600 replaced the 6.5 beginning in 2000, however a version of the 6.5 (6500 Optimizer) is still produced by AM General for the HMMWV(Hummer). There were several versions of the 6.5 produced over the years. Almost all featured a turbocharger, only about 1 percent sold were N/A versions. Biggest changes came from emissions and fuel injection changes to meet standards.<br /><br /><span style="font-weight: bold;">Specifications<br /></span><ul><li>Engine RPO Codes: L49, L56, L57, L65, LQM, and LQN.</li><li>Displacement: 6.5L / 395 cu in</li><li>Bore x Stroke: 4.06 x 3.82 (in.)</li><li>Block / Head: Cast iron / Cast iron</li><li>Aspiration: Turbocharged (Borg-Warner GM-X series) Also available naturally aspirated.</li><li>Valvetrain: OHV 2-V</li><li>Compression: GM Early 21.3:1, GM Late 20.3:1, AMG/GEP Marine 18:1</li><li>Injection: Indirect</li><li>Power / Torque (lowest): 180 hp (134 kW) @ 3,400 rpm / 360 lb·ft (488 N·m) @ 1,700 rpm</li><li>Power / Torque (highest): 215 hp (160 kW) @ 3,200 rpm / 440 lb·ft (597 N·m) @ 1,800 rpm</li><li>Max RPMs: 3,400</li></ul>Rickhttp://www.blogger.com/profile/04332444330276920257noreply@blogger.com0
