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

I wouldn't go as far as saying the LS9 is BETTER than the LSA. More powerful yes, but better I don't think so. Each engine, for their power rating, is just as reliable and the LSA is even a tad more efficient. So it really depends what your definition of
better is. If better to you is more powerful then yes LS9 is better than LSA, but the LSA is still a damn good engine.
