    I'am just thinking about it. Is there an aftermarket harness out there that will mate up to the Vortec motors and make the install easy to put in my 85 K5. I have a 91 stock T.B.I. motor in my truck now that was a pain because I used the 91 harness and tied it into my 85 harness it was more work than I wanted. So let me know it if you guys know of anyone and how much$$$$. THANKS /forums/images/icons/grin.gif

    There is a Vortec TBI intake out there. Replace the intake w/ this one and bolt on your TBI.

    98 is doable if you want to. 99 isnt really. Thats the new motor.

    The problem w/ even the 98 is that there are sensors all over the truck. Trans, Tcase, axles, exhaust, brakes, New pump, ETC.

    I am sure it CAN be done, buts gonna be pricey. Check w/ Painless wiring.

    I think the key year to get would be 95. No OBDII, that means a whole lot less sensors to have to mess with, and it is still an actual Vortech

    IIRC Vortec motors have been around for a while (89 maybe) but the Vortec heads that everyone wants are I think 97 and 8 only. The easiest way to ID the good heads is that they have only 4 bolts per side that are vertical. 2 in front and 2 in back. None in the middle.

    <font color="blue">Vortec is 96 and later. The 95 motors are TBI and are the same thing as an 87 motor.

    Biggray71 confirmed want I thought was correct. I have a '95 Silverado P/U, it is not Vortec. All of our shop trucks that are '96 and later are Vortec. /forums/images/icons/grin.gif

    Billy, honestly man don't do it. It's way more trouble than it's worth. I'm putting on in at my shop right now and i swear to god i'll never do it again. NEVER!!!!!
    You'd be better off to buy a good long block from Scoggin Dickies and buy a Multi Port FI kit to go on it.
    Of course i may just be a dumb $h!t that doesn't know his a$$h0le from his Belly Button. /forums/images/icons/smirk.gif

    Hey Billy,
    I'm just about done with this swap, 5.7 vortec and a 4l60e tranny from a 99 tahoe into my 87 Jimmy. This is not a trivial swap but I think in the end I'll be very happy with the results. As for the wiring, yes there are a couple of companies that make harnesses for this swap for around 600 bucks but the stock harness is very easily adapted to work in an older vehicle. I haven't completed the wiring yet but I think that it's going to be one of the easier phases of this project. The truck goes to the exhaust shop this week and I sent out the computer to be reprogrammed this morning. If you have any specific ??, let me know.

    Later,
    Mike
