  • Holley 502-3

    I've used the Holley TBI for several years now and I don't like it. I have never been able to get it run the way I want. "betterthanyou" has spoken in length of the 4.3 TBI. I have a 4.3 p/u and the throttle is on the wrong side to use on a 2.8. Plus, I had to change the wires on the Holley and don't remember how the stock ones went.
    I want to dump the Holley and get a 4.3. Does anyone have one set up to go on a 2.8(3.1 hybrid)?

    Plus I have a 3.1 reground crank and bearings with .030 iron head pistons I don't need. Also an Eaton Lim/slip for 3.73 18 spline I would like to sell or trade.

    I have some. PM me. I will clean it, modify the throttle arm and also install the missing vacuum line. Its $175 CDN with shipping included. I also sell the bored out intake with it along with the gasket for $375 with shipping. The intake will be cleaned and bored on a milling machine and I will remove the casting flash from the runners and blend the throttle bores into the plenum.
