Rocker Arm Ratio
What is the stock rocker arm ratio in 6.0 LS2 engines. 6.2 LS3? I tried to find it online. Found lots of articles on such but just the stock ratio. Any thing offered by factory that adds a few horses. I gather they are a 1.7 ?

All LS series engines, except for the LS7, use 1.7:1 rocker arms. The LS7 uses 1.8:1 but they are not interchangeable. There are aftermarket rocker arms that are 1.8/1.82:1 avaialbe for the LS series engines.
