Need advice from those in “the know”. I’ll start by saying I purchased new an 06 LBZ and owned it for 3yrs/ 50k miles. Sold it when I quit racing, and missed it ever since. After owning a few gassers, I want another LBZ. They’re priced like gold still down here in socal. Found a 06 2500HD 4x4 (9/05) build date with 170k. Guy is second owner, no towing. Previous owner added 5th hitch and airbags, sold at 145k. Im thinking its pulled some weight. Fully loaded LT3 pkg. He accepted 18k though it needs tires. I ran truck, upper hose stayed easy to squeeze, no engine light, clean truck. Im somewhat mechanical but looking to avoid HG replacement and Trans rebuild if possible. Shall I scoop it up or keep looking?. Stock exhaust and no tuner that I saw. Thanks in advance!
