At wot or part throttle? Does it boost lag right off idle or is it instant like the v8 it replaced?
I probably won't know until i drive one off-road.
I drove the first revision a few years ago in the silverado when it had less power, from what I remember it was pretty good off the line, no real lag. Where I noticed a lag was when coasting in the city and then gunning it, there was a fair amount there and part of that was probably transmission tuning, that 8 speed is complete trash. The new 8 speed is supposed to be a lot better and that is the one that is used in the new colorado and also the new silverados. Not sure what year they made the switch.
Also this engine didn't replace the v8, it was designed to replace the 4.3 v6. It completely dominates that older v6 in every way, much more powerful, better fuel economy, cheaper to build, lighter, stronger internals.
The fact that so many compare it to the 5.3 v8 shows just how good it is, that wasn't the original design/intent.
