The VQ37 may last longer under boost or other forced induction but under stock conditions, I'll take the motor that doesn't overheat when I want to drive fast.
Let's not forget the 370Z's insane road noise when you are driving. It sounds like you are sitting in an 80s Pathfinder with the interior removed. I have to yell to talk to the other person in the car when driving. The 350Z is much more civil.
Two words: "oil cooler". Even the 350Z needs one at the track, just do a search on their forums. The 370Z is BA at the track, and in smaller tracks, without very long straights, can even beat the E90 M3. Here is a clip of a guy, who I rode with at a race track running a 1:51. He is an intermediate level driver, and the fastest I've seen a stock M3 go at this track is 1:55.
370Z stock except for Stillen CBE, high flow cats, and an aftermarket oil cooler (1:51)
Stock E92 M3 running it's typical time (1:55)
