Anyone know if there is any validity to this?

Well, I hope they introduce an 8 speed behind the 6.4 before that happens. Then I will be set for a while. I'll go back to a Cummins before I run some pissant turbo POS. I, for one, do not have Eco Boost envy.
There were rumors of a 4.8L V8, maybe based on the Petastar V6, to replace the 5.7 Hemi. However, now the rumor is (yes, rumors of the rumors, I know) that the 4.8L idea was scrapped. Supposedly they have a lot of 5.7s stockpiled to last until they no longer offer a V8. We'll see if they update it a little to increase HP/TQ.
not sure if the vocabulary matters, but i believe the 4.8 engine was shelved, not scrapped. on paper, it is a great engine, capable of matching and exceeding hemi numbers, but more expensive to build.
Interesting. Was the 4.8 to be NA?
I can say the 5.3 in my 2015 Silverado had A LOT of juice. It ran very strong once you got it past the stupid gm lazy throttle response and torque management. At wot or near wot, i was all smiles. No question it would out run the old 5.7 gm V8 in the older pickups.
