i have a 4x4 99 burb for a family ride. its a 5.7 vortec with 269k on the vehicle. i di replace the motor about three months ago. if i were going to built it for basic trailing id do a 2 inch suspension lift and a 2 inch body lift. with 285's. it should come with a factory rear locker, mine did. if it were not for the wife not being on board with it id built this for sure. oh and id add a winch. but even stock this thing has surprised me several time in what it was capable of. 4lo and let it crawl. maybe if i wheeled it more i would consider a front locker.
