Looks like Ford bumped the 3.5 to 440 recently. Hard to say if they tweaked bits in the 3.5 to run that or not.Great info!
Regarding the SR engine spec, peak HP and TQ are at lower rpms; 2,400 and 2,000:
Horsepower i-FORCE: 389 hp @ 5,200 rpm (SR: 348 hp @ 2,400) i-FORCE MAX: 437 hp @ 5,200 rpm
Torque i-FORCE: 479 lb-ft @ 2,400 rpm (SR: 405 lb-ft @ 2,000) i-FORCE MAX: 583 lb-ft @ 2,400 rpm
Weights are about the same as current I believe. I knew the F150 was light, but didn't realize they GMs were.
