Noticable difference between 5.3 and 6.0?

I went from a 4.8 to LQ9 so I can crime in. Don't let anyone tell you the difference is huge, it's not. Basically the 6.0 feels like the amount of power that should have come stock. The nicest difference for me was highway cruising power. The ability to go up any hill without dropping out of OD is nice. a 5.3 in a reg cab is probably very similar to the feel of a 6.0 in an ext. cab such as mine. The 5.3 is a very capable engine, as many have proven. That being said, I'm biased, and I would do the 6.0 swap :dancenana:

Im going to go with an lq4 and the torquer cam mentioned. Then if I need more power down the raod I can boost or spray.

FWIW my almost stock LQ4 is nearly 100% on injector duty cycle.

Thanks for the heads up Nate.
