> **New Pistons**  
> LS6 pistons are cast from high-strength M142 aluminum alloy and reshaped with a slightly different profile than those in the LS1. In side view, the LS6 pistons have a slight barrel shape, almost imperceptible to the naked eye. The new alloy increases engine durability at racetrack operating levels, while the shape reduces internal mechanical noise.

weird…never heard about that

anyways, Power level abilitys are about the same on both motors. 600rwhp-650rwhp on both is the “safe” point…with a few 700rwhp’s not having a problem.

once you upgrade the valvetrain on the LS1
