This is an LS Swapped 6.0 LQ9, 4L80 transmission Sierra with 4 wheel disc brakes. The work was performed before I bought the truck, and I've been driving it as a daily driver for a year now. Great truck, very quick, and very good looking. I have entered the truck in small local shows, it is very presentable. Engine is an LQ9 with LS3 heads. I do not know camshaft details but it is obvious after startup that it is not a stock cam. It uses a GM PCM that can be tuned with the very common HP Tuners software. It does pass Texas state inspection. HP estimates were given to me but I don't want to offer those up because I haven't dynod the truck. It will easily outrun a stock 14 V8 Camaro but otherwise I drive like an adult. The body has no dents, paint is excellent, I had it professionally detailed last January and will have it done again this January (2017). The bedliner is a professionally done Line-X and it looks great. I do have a couple of hideaway hooks in the bed so I can use it without damaging the rails. There are a couple of small screw holes on the bedrails, no rust. The interior is stock other than a stereo with subs under the seat, and an amp behind. It's plenty loud to listen to music over the exhaust. The gauges all work just fine (an issue with amateur engine swaps). Obviously the suspension is lowered, and the truck handles pretty good. Air shocks in the rear hold air for months. The wheels don't rub, it drives just like any lowered vehicle. Has slotted drilled disc brakes all around that stop great. Over the year I've made a list of things that aren't correct about the truck. I want the buyer to know exactly what to expect so here they are: No A/C compressor. Where it mounts on the Escalade would be right in the framerail on this truck. Everything else is there. I'm not in the know, possibly there is a nice bracket for this, I'm just not inclined to worry about it. Oil pan leaks and needs a new gasket. On the first startup, it needs to be held in drive for one second to idle smoothly. When the tank gets close to empty, the truck will stumble on hard throttle, just need to keep 1/4 tank or so. There is a small tear in the seat bottom on driver's side. Headliner needs to be redone. One cut in steering wheel. The aftermarket power door locks sometimes don't lock when it's very cold outside. For folks that are seriously interested I'll take photos/videos of what you need, answer any photos that I can.
