I bought this 2004 a year ago and drove it a little before accumulating the parts needed. then I did the swap. LS2 6.0 with aggressive cam making 470rwhp that has all new bearings and gaskets mated to a t56 with monster 3 clutch. rear end is IRS out of a skyline gts-t yes its independent rear and its awesome. Viking double adjustable shocks in the rear. kirkey seats, c7 z06 replicas and drag wheels are gto spares and race star rears. all gauges work and are accurate...everything works as if factory the a/c is not hooked up but its wired for it. doesn't leak a drop or smoke. drives great. body is 5.5 out of 10..it was a work truck, has scratches and some surface rust...cleansup nice just not show quality. just needing to free up some cash for a plow truck this year. open to trades on duramax only. call or text with any questions 513-410-1446
