    Winter approaching...and ive been giving the switch from carb to fi some serious thought.

    How practical of a switch is this? Even just to a stock tbi, mabye find someone who wants to trade. What all will have to come off my truck for it to work?

    For the swap you will need:
    Complete TBI setup,ECM all sensors and wireing harness.
    TBI distributor. your HEI dist wont work with TBI
    TBI Manifold or adapter plate.
    TBI fuel pump
    Plumb fuel return line back to fuel tank.
    You can get all this stuff off a donor vehicle or buy complete aftermarket kits.

    These guys sell complete bolt on kits minus the dist for around $1200

    Yep, it ain't cheap! It would be way cheaper to just fix your carb so that the choke works properly. /forums/images/graemlins/wink.gif

    yea, but then you have to deal with its issues: hacked harness, bad sensors, nasty TBI, etc etc. Going new is nice. Going used is kewl too if you have the time to sort thru the harness and sensors.

    I have gone both ways. I installed a new EFI system on my BBC, and since then replaced the BBC with a donor '91 350. I had ALL the parts required, and a pretty good harness to work with. It still took me an entire day to sort thru the harness, and eliminate what I didn't need - and I had pretty intimate knowledge of the ECM's harness prior to getting into it.

    If you get into the project, be sure to check my site for info on the ECM harness! /forums/images/graemlins/grin.gif
