It depends on what people are expecting from this truck. Who buys a diesel pickup to do empty 0-60 runs? I've no doubt a 5.7 hemi would clean my 6.7 Cummins 0-60 empty but which am I going to choose to pull my 5er? HP rules when it comes to flat out performance but low and mid range grunt is preferred for towing and daily driving in traffic. The normally aspirated gas engine's narrower power curve will also probably benefit more from the eight speed transmission than the turbo engine in a drag race.
The torque curve I found shows the 5.7 hemi making 330 lbft at 2000 RPM. That equates to 120 HP. The 3.0 diesel's 420 lbft at 2000 RPM has it making 160 HP. Unless you are in perpetual boy racer mode, more of the diesels power will be usable even though it won't win many drag races.
I also think this engine will get better mileage. When you compare the Audi, VW and Mercedes 3.0 turbo diesels to their gas counterparts in the same vehicles, they all get at least 20% and in one case 28% better combined mileage according to the EPA.
