I'm not denying the LSx. But the first arguement outa any GM enthusiast is "Ford had to use a blower." Why discredit them for using small cubes and boost to make the same power? The internals in the Ford motor are better than any LSx, minus the LS9, from the factory also. Yes the LSx's respond far better to nitrous, they have a better head design. Which is funny since its 2 valve versus 4.
As far as V6's go, they're not even on my radar. I give half a shit how much power the new GM V6's make, because I know what the aftermarket support will be like.
Don't get me wrong, I'm not puttin one above the other (Ford vs. GM), I say I give Ford more credit than GM yet I drive a GM. Id trade it for a 03/04 Mach 1 or Cobra, but Id trade that for another GM. Lol, I like em both, and hate em both.
