Description

Premium 356T6 aluminum material designed for the Supercharged LSA engine. GM engineered this LS cylinder head for the "power adder" of forced induction on the LSA engine with a unique "swirl inducer" in the intake port for improved combustion efficiency. GM Testing showed that this intake port design requires less timing while providing improved horsepower gains over the conventional LS3 style intake port in these applications.
