At what RPM does the 2.7 develop 325hp? What is the torque band of the 2.7 like? 325hp and 87ftlbs of torque at 7000rpm?

Quite the opposite I believe. The 3.5eco maxes 420tq at 2500rpm. The 2.7 is rated at 375tq and should have a curve simmilar to the 3.5eco.
Anyone who has driven an eco-boost f150 knows theres an abundance of low-end grunt. The 2.7 should be simmilar just a bit softer.
I have always been interested in engine technology and this thread spurred some reading on the internet last night. The 3.5 EcoBoost actually has a very impressive power/torque band! 420ftlbs is a pretty good torque rating... ehh. 420ftlbs at 2500 rpm out of a 3.5l engine is darned impressive!
I did some reading on the 2.7 EcoBoost too. I found that Ford went from the light weight aluminum block in the 3.5EB to a graphite impregnated iron block in the 2.7 EB which is even denser than normal cast iron blocks. Very interesting and sounds quite impressive from an engineering perspective.
I didn't realize the 3.5 EB runs a 10:1 compression ratio... on a induced induction engine! Very impressive and made viable by the direct injection system without having to go to ultra high octane levels or water injection to control pre-detonation.
To me it doesn't sound like GM and Chrysler are doing a very good job of keeping up with Fords technology in this particular market segment.... Although that small Dodge diesel does look impressive. GM....???
