I’m actually doing an ls swap in a 1986 c10, I picked up a 2005 5.3l out of a silverado, 4l80e came off a 2008 6.0. I’m going for decent power nothing crazy. I’m thinking about throwing in a cam and maybe a bigger intake and throttle body.
Currently doing an LS swap on my 1986 chevy c10. I’m needing some help to make sure my set up will work together. I’m looking at a 2008 4l80e transmission to go on my 2005 5.3l. Will they work together and will a standalone harness for a 4l80e work
