So- it seems like the ACE solution for an LS swap into our rigs is over- kaput- no longer available, etc. etc. Does anyone else have a kit that will bolt an LS (and maybe the 6L80 6 speed GM transmission) into our rigs? I found RW Engineering's page- looks interesting- motor mounts and a transfer case adapter- I emailed them and got an initial response about them installing an LS for around $20k- but no response when I asked about the components for DIY. Any reasonable and decent products out there that can tackle this properly with a full kit and wiring harness or is this just a new business opportunity for me to get dialed in? ¯\_(ツ)_/¯
Check out Mark's 4wd. They have a kit for the D2 that places the transfer case in a bit better position than RW's kit. Wiring.... You are pretty much on your own. Any standalone LS harness would work, or build your own. The main issue is retention of traction control and gauge functionality. It is possible, just not as well documented.
