Question Reliability of new Vortec V-8's (4.8,5.3,6.0)

Hi all, I'm going to be in the market for a new used truck soon, like probably within a month or less. Going for a 99/00/01 Chevy/GMC 1/2 or possibly 3/4 ton 4x4 ext cab shortbox.

I was just wondering if anyone knows of any major issues w/ the new V-8 engines that come in these. I know I've heard of lifter noise and oil consumption problem I think, but don't know of anything else. My parents used to have a 00 1/2 ton w/ the 5.3 and the motor blew up w/ less then 30K on it. I don't know what exactly happened, all I know is they were told it dropped 3 cylinders, they were in New Mexico when this happened and had it repaired under warranty.

So any help on this would be great. Also how is the 8.1L big block in the 3/4 tons? like gas mileage as compared to the small blocks and reliability as well. Thanks

Ean
