One reason the LS motors will fit where others won't is the relatively small heads. An Audi V8 with DOHC cylinder heads might well be heavier and certainly would be larger and harder to fit in the engine bay. Even though the LS "only" has pushrods, the redline is within ~500 rpm of my '00 S engine ... and the car would probably be faster even shifting at 3500. The only downsides I can see to the LS motor are that the CG of the motor would be higher, and it wouldn't make those sexy flat 6 noises.
