I would agree with that.
A naturally aspirated engine will always last longer then one with a turbo or supercharger.
The hurricane twin turbo is closer to the 6.2L and not counting sound should be a complete upgrade.
But comparing it to the 6.4.... The 6.4 should last a a much longer time without needing to be ripped apart and rebuilt.
I still don't see a reason why they are going to offer a straight 6, and not offer the SRT though. How is that any different then the Pentastar, hemi, and ecodiesel they offer now? 3 completely differnet engines on a 1500. I think they are getting rid of the ecodisel on the 1500s right? Are they going to offer a Pentastar and Hurricane only? My as well buy a Ford at that point they have more experience with v4-6 and turbos then Ram and will far likely outlive a g1 Hurricane.
Just make the Hemi standard, Hurricane an option, and an SRT as an option. It's not rocket science.
