The new 4.3 V-6 provides 285HP only when burning ethanol gas and as a result of the lower energy value of this fuel the MPG drops from 19 for the old 4.3 engine to only 13 MPG with the new one. That is a lot worse than what one can get with the V-8. No free lunch as the old adage goes.
According to the GM Powertrain website, it looks like the new 4.3L is rated at
297HP with E85. The 5.3L jumps to 376HP.
Brassica, congrats on the new truck. It should do a great job towing a 4000# trailer.
