    Info on ls swap

    I have a 1998 z71 with 5.7, I want to put a 5.3 in it..I have the motor, harness, ecu and manifolds. I'm trying to get a exact parts list and find out what needs to be done with the wiring as well. Thanks in advance, troy

    There is a really good sticky on here that lists out a lot of the parts you'll need. Good luck with the swap!

    I'm in the middle of mine now. You need dirty dingo motor mounts and there is several ways of going with wiring. Take it off the motor completly and go through it, take out what's not needed and rewrap it and put it back or just cut the plugs and only wire the stuff you need. Also you can't use the A/C on the 5.3 unless you use the relocation bracket. I don't know all about it cause im not running A/C but its what I've seen people have to use.
