If you drive the Chevy/GM, make sure you drive the 6.2. I had the 5.3 and friggin hated it. It was gutless. I was coming from a diesel and just thought gassers were like that. I regretted buying that truck with the 5.3 the minute I drove it off the lot. I should have gone with the 6.2. Make sure you at least test out both engines if you try out the GMs.
^This is good advice. I was initially disappointed with the 5.3. It did feel gutless compared to the 5.7 vortec I had back in '97 - that truck was a beast and a blast to drive. I finally sprung for a Diablo tuner for my new 5.3 and it feels like a different truck now, lots of power and even gained a little mpg. I guess they're just tuned too conservative from the factory. I also turned off the AFM (turns off 4 cylinders when cruising, supposedly to save mpg's). That particular feature has been found to burn oil and crap up the inside of the engine after about 90k. Plus it seems to hesitate when you step on it and it has to turn those other cylinders back on.
