Chevrolet Performance LS 376/515 6.2L Crate Engine

DescriptionAffordable LS-based high performance for the street or trackUsing the LS3 engine as its foundation, the LS376/515 crate engine adds Chevrolet Performance’s racing-derived ASA Cam and a carbureted intake system to produce 533 horsepower at a stellar 6600 rpm and 477 lb-ft of torque at 5200 rpm. It’s the perfect high-performance option for a classic project car or racecar.The assembly includes a Corvette oil pan and LS3 cylinder heads, with high-flow, rectangular-port intake passages, as well as our unique, spider-type carburetor intake manifold. At the heart of the engine is the ASA cam, which extends the performance range of the LS3 with more duration. That means it holds the valves open longer, enabling greater airflow at higher rpm. Wind it out yourself and you’ll see what we mean.You’ll need our LSX controller (P/N 19171130) and Holley 770-cfm carburetor (P/N 19170093) to finish off and fire up this bad boy.Tech Specs533 HP @6600 RPM477 LB-FT TorqueEngine Type: LS-Series Gen-IV Small-Block V-8Displacement (cu. in.): 376 (6.2L)Bore x Stroke (in.): 4.065 x 3.622 (103.25 x 92 mm)Block (P/N 12623967): Cast-aluminum with six-bolt, cross-bolted main capsCrankshaft (P/N 12597569): Nodular ironConnecting Rods (P/N 12607475): Powdered metalPistons (P/N 19207287): Hypereutectic aluminumCamshaft Type (P/N 88958770): Hydraulic rollerValve Lift (in.): .525 intake / .525 exhaustCamshaft Duration (@0.050 in.): 226° intake / 236° exhaustCylinder Heads (P/N 12629063): Aluminum L92-style port; “as cast” with 68-cc chambersValve Size (in.): 2.165 intake / 1.590 exhaustCompression Ratio: 10.7:1Rocker Arms (P/N 12569167 int): Investment-cast, roller trunnionRocker Arms (P/N 10214664 exh): Investment-cast, roller trunnionRocker Arm Ratio: 1.7:1Recommended Fuel: 92 octaneMaximum Recommended rpm: 6600Reluctor Wheel: 58XBalanced: Internal
