GM might be right in their determinations that all they have to do is change combustion chamber, add DI and VCT to their small block, all of that may be true. I just get the feeling that they are designing an engine for now, not 2016 to 2020 fuel economy targets.
This is why I think Ford is in front of the curve with the 6.2 Boss and 5.0 Coyote, Ford knows that
ultimately smaller engines and DI turbocharging will replace their large V8s but they need a transition for
the technology glide path and that will be the blown Coyote and Duratec 35......
Ford are already way in front of GM, they know where they are going after Coyote....
