'17 3.5 EcoBoost is a COMPLETELY NEW ENGINE. The only thing the same as the '11-'16 3.5 EcoBoost is the displacement. It has direct injection AND port injection (keeps the top of the valves clean). Also note that the '17 2.7 comes with the 6 speed transmission. The '17 3.5 comes with the 10 speed. Be careful which one you get. First gear with the 10 speed with a 3.15 will be about the same as a 3.55 with the 6 speed.
I have 90k+ miles on my '13 3.5 EcoBoost 3.55. Had to replace a boost pressure sensor at 85k. No other engine system problem. I'm very pleased with it as a tow vehicle and as a daily driver.

The standard 2.7 EBs have a lower payload than the standard 3.5 EB. Know what you are buying.
