Read the speed figures on all par iirc.
I agree, in a truck if any towing or heavy it's not the engine to have.
I really think they are fixing to make a competitor for the Eco boost if it continues success.
I have a hemi now, I love it. I got 33" duratrac's and 2.5" lift and the truck still banged of 20+mpg on my last 3 trips (last 3 weekends)
So I don't see that as an issue.
I think they'll be fine for certain buyers. Honestly though I had no beef with the outgoing 3.7l. I had one in a Dakota I found it exceeded my expectations.
As for the v6 balance thing:
6x60 deg =360 deg. No issue
Lots of v6's with 200k + miles on them.
The v6's on 90deg config with split pin cranks have had varying degrees of success
What's long overdue is some love for the 4.7, and a bigger v8 in the 2500 and up trucks.
Silence! Differing opinions will not tolerated
