When my 5.7L had Pete's intake cams, I really thought it was a very sweet motor. Very smooth. And it was. I was concerned about adding the exhaust cam being too much, too lumpy, too raucous.
NOW, it is just perfect IMO. So tractable, so driveable. It does exactly what you want it to do and when. It would be difficult to go back. And so if I were to go to a larger displacement LT-5, I couldn't imagine spending the money without doing the cams. If anything, the larger displacement NEEDS the bigger cams to take full advantage of the additional cubes.
