The LSA uses hypereutectic pistons while the LS9 uses forged pistons. Also the connecting rods in the LSA are powdered metal while in the LS9, they are forged titanium. The valve train in the LS9 is also a lot better. Basically, the LS9 is built to take a shit load of abuse with all its forged internals. Not to mention the LSA has a super tiny .480 lift cam while the LS9's cam is .561 I believe. There's many differences between the two. The LS9 is without a doubt, the better engine
