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.
