Power limits for LA small blocks?

The biggest reason that the LS has such aftermarket support is because its largely an improved design on the 350 small block that has been around for damn near 60 years. meaning there is millions of them out there. Never the less, they still cant beat the HEMI design.
Actually the LS shares absolutely not one single part, measurement, or design of the old small block Chevy.

Now bear with me... I'm not a Chevy guy looking to stir up crap on a Mopar board. I like all makes. Right now in my garage an LS and a hemi are currently cohabitating and I'm pretty well experienced with both engines. I personally can't think of even a remote hint of an advantage the hemi has.
