dave the vortec max is pretty much the 1500 for all out pulling.
jeremy if i'm not mistaken (and i can be) wont the ecoboost out pull the big ford v8?
It might - but the 6.2 is the biggest offered in the F150, it has the highest hp and torque.
Ford doesn't offer any direct comparisons on their own line up.
I've decided to hold off on a new truck for a year - other things take priority right now. I'll revisit the ecoboost and gm at that time.
Definitely drive an ecoboost if you get a chance - it's pretty impressive.
