Cool... im just saying claimed WHP does not matter in these informal street comparisons unless accompanied by dyno sheets from the same dyno with the same conditions... I could claim I dynoed my E90 at 250whp and go on to beat someone with an E46 making a real 270whp in some random youtube clip.
I don't know LS motors... however I would imagine that NA mods like cams, higher compression, and bore/stroke increases would increase power... those would be considered internals right
