Any other questions feel free to ask. I would do this swap again in a heartbeat, it runs awesome! I just wish I would have started with a better shell.

OK....so you didn't have to use the harness from painless? I am doing a similar swap but I am using a vortec 454 from a 1998 2500 in my 1991 burb. But you probably ran into the same issues as I am about to. I have been told I can't use the stock harness and have to go with a custom made one from painless or Howell. These are Howell techs that have told me this and I almost believed them until I saw this post. If you used the stock version, I'd like to see pics on how you ran your dash connections with as much info as you can give. I will contact painless on their "auxiliary fuse box" thing a ma jig and see if it can work for me. Did you need your computer to be re-programmed? I am so close to finishing my burb. The vortec 454 is in along with the computer. I need to put the 4L80E tranny and NP-241C transfer case(passenger side drop) in and finish the wireing. The wireing is my biggest hold up so far. But I have the ODB2cats ready for the dual exhaust setup as well as all four 02 sensors that are brand new. What else can I be missing?
