Show original supplier description
The GM 19540155 is a 6.2L LS3 crate engine, also known as the LS376/430 HP. This engine delivers 430 horsepower at 5,900 rpm and 425 lb-ft of torque at 4,800 rpm. It is built with a cast aluminum block featuring 6-bolt, cross-bolted main caps for enhanced rigidity and performance. The heads are designed with 63 cc combustion chambers, 2.16-inch intake valves, and 1.59-inch exhaust valves to optimize airflow. Its camshaft offers an aggressive .551-inch lift on the intake side with reduced overlap compared to the LS2, further improving airflow and power output. Rocker arms with a 1.7:1 ratio are integrated into the heads. This LS3 crate engine was the standard engine in the fifth-generation Camaro SS and C6 Corvette, highlighting its performance pedigree. It is described as a high-revving, deep-breathing engine ideal for street rods, muscle cars, and resto-mods. The engine utilizes L92-type rectangular-port heads and maintains a 10.7:1 compression ratio. For optimal operation and longevity, Chevrolet Performance recommends using specific engine oil.
