74' Squarebody Gen V L83 - 6l80 Swap
I got a good deal on a 2016 l83 with 6l80 transmission from a Sierra and will be swapping it into my 74' 2wd square. I am just trying to gather up as much info in one place as I can as far as what mounts, trans cross member, headers etc.. that you used to keep everything in stock position as possible. Also tips in doing the harness yourself it someone that can strip it fairly inexpensive, floor shifters etc..
Any information or good links to read up on would be greatly appreciated.
My goal at this point is to leave it stock with exception if headers and a good tune. Also can the truck trans be set up to use touch shift or is it even worth doing.
