Based on the EcoBoost engines I have seen, you can almost double the effective "displacement" of an EcoBoost engine. IOW, the 2.7L EcoBoost performs like a 5.4L engine, and the 3.5L EcoBoost performs like a 7L engine. The second generation of the 3.5L EcoBoost is now producing ~~ 470 ft-lbs of torque, and it's still a flat curve.

Originally posted by jato Thanks GlueGuy !  Next question is how long can one expect an ecoboost engine to last in miles, such as the 3.5L?  Curious as my 94 F-150 with a 5.0L V8 is beginning to get a bit tired and rusty with 315,000 Michigan salt miles on it.  Also the 31 deer kills have not helped either, nor all the other "hits" (I haven't kept track of those) where they only got maimed and limped off the road.

The bottom end (crank, journals, and piston rods) on EcoBoost engines are built like diesel engines. Both the 2.7L EcoBoost and the 3.5L EcoBoost are built with 6-bolt main bearings (that is not a misprint). In the "old days" one sign of a so-called bullet-proof engine was the use of 4-bolt mains. Well, these engines are built very seriously. The original EcoBoost engines have been around almost 10 years now (first production in 2009 for the 2010 model year), and it looks like Ford is going all in. Their track record is very good by all accounts.

Leo, the engine is still very strong as well as the clutch and throw out bearing.  Main issue is with the deteriorating body, getting a fair amount of rust, especially in those areas where deer have met their doom.

Thanks coyote, that is good info to know.  Think I will start casually looking at used Fords with ecoboost, was 2013 one of the first years they installed them in the F-150?

If I could afford to buy a new Ford 150, I'd do it.  But in the meantime, I'll manage with our Dakota.
