    What?s it take? Gen 3 5.3L with 6L80

    So I’m working on a custom build and would like to go with the 6L80 behind a gen 3 5.3L. I’m curious what it takes to match this combination up? This will be going into a 63? C10 pickup. And yes I?d like to stay with the 5.3L. I’m going to put a small supercharger on the 5.3l. I?m not looking for crazy HP so this setup seems pretty streetable.


    Would really appreciate the help!

    You could swap the reluctor on the 5.3 to a 58x and use a E38 ECM.
    Use the LS1 pcm with a TCM-2650 controller for the 6L80
    Or you could use a Holley terminator x max for a 24x engine with their 558-499 6l80/6l90 controller
