I have a 02 silverado 1500 lt extended cab ( you can ride back there not like the ford)with the 5.3 and automatic. 35k and no problems at all(no piston slap). I really like this truck it has a lot of power 285 horse at 4000 rpms( 3.72 rearend). most trucks and cars i have bought i got tired of right away . i have owned this truck for 2 years and still like it. I get a honest 18 m.p.g.
