The 6.8 is said to be Patterned after the push rod 7.3 Godzilla V8, guess we will see when they come out won't we, as for cylinder deactivation nothing was said about THAT in anything I have read to date outside of ford doing that on the 5.0 in the F-150, How about posting a LINK to back up your cam phaser / cylinder deactivation claim on the 6.8 V8.
Considering the 7.3 Godzilla has camphaser and VCT I’d say the 6.8 most definitely will too lol. The 6.8 is just going to be a shorter stroke performance version of the engine with more power.
