5.3 liter swap into 83 Chevy
« on: October 24, 2012, 08:27:09 pm »
I'm considering buying a 5.3 and swapping it into my 83.  Has anyone done it or know how much of the ECM and harness I would need to pull from the donor truck?

You need ALL of the wiring from the donor, don't let them cut anything.  Ask for a take-out motor.
