    Hey fellas Im looking for a little info, One of my trucks is a 90 K2500 with a 350 I bought a Holley TBI for it but the Holley TBI has a round TPS plug and the stock TBI has a flat plug, question is, is there a plug I can buy to go to the round style and if so will the wires match up?

    before you install that unit go read some good info on www.tbichips.com brian has lots of good info.

    its realy not a simple bolt on item all stock for stock. will require some mods to work right.

    right on the money. a better option would have been a modified stock throttle body, like XtremEfi on EBay, RV Morse, CFM Tech, or TurboCity.

    there is a lot of more user freindly options before holley tbi unit.

    i have one but i am going to use it on a 454 big block swap over. and its super close to the 454 tbi specs. but much more price and finding friendly rather than a 454 tbi unit.

    go read brians stuff on tbi chips.

    to much work to work right on stock stuff.
