They start out with a cast aluminum 6-bolt engine block with cross-bolted main caps and add a nodular iron crankshaft, powder metal connecting rods, and 10.7:1 compression ratio hypereutectic pistons. They also include a pair of aluminum LS3 rectangular ports, 68cc cylinder heads with 1.7 ratio rocker arms, a GM Performance Parts hydraulic roller "hot cam" and lifters, and a carbureted intake manifold. Those parts allow the GM Performance Parts LS 376/515 HP LS3 crate engines to provide you with a powerful small block that can be driven on pump gasoline.
Greg,
I've seen this engine in the GMPP catalog, what it does not include is the distributor drive kit and the acessory drive hardware. Also, I believe that it used the ASA cam which specs out differently than the Hot cam. This moves the peak torque up to 5000 rpm vs. 4500 with the Hotcam. The lower peak torque rpm of the Hot cam is more street/autocross friendly IMO. Actually, I wouldn't be surprised to see GMPP start to offer LS shortblocks soon, so that you can pick a set of heads and cam without tearing apart the engine first to optimize it for your application.
