My ls6 will smoke my m3 anyday on the track without even coming close to it's limits. I pass up higher power porsches and vettes easily (mainly out driving them). I keep up or pass them in the straights.
of course I enjoy my m3 much more. much less nvh AND it has air conditioning.
I think speaking from experience weighs more than any theoretical rambling here....
I road in a LS1 powered Miata before and the overall feeling was OMG WTF I am going to die. The rear end starts burning rubber with every shift and it hops like a maniac all over the road. Corner, step on the gas with the stock Miata wheels and you go spinning real quick.
That said, I don't get the same feeling in my friend's LS-powered 240SX. It just feels right in that car but then he is running some big r-comps.
