It's funny you say that when the 6.4 was designed to rev out.....it will outperform the UR engines up high. Both the Hemis and LS have this weird reputation of not being high rpm capable and it's interesting why everyone thinks that just because they use pushrods.

The X5 is essentially the same vehicle but it feels way more agile.

The Toyota 5.7 has a better rumble, though. And it's not as if the 5.7 isn't smooth....just, USA knows what they're doing with their old school V8s. I'd love a GM 6.2 minus the efficiency crap that gives it issues.
