Can't remember the magazine that posted this, but there was an article that had dyno numbers from JUST a cam change, albeit a radical cam, that gave the 5.3 an additional 96 horsepower. I think if you put in a mild cam you should be able to gain 40 hp and close to that in torque AND gain mileage. I think all the other stuff would be better first and then the cam, just as Glock said.
