    i got a tbi 454 out of an 89 1 ton (along with a dana 60!) and was wanting any advice. i dont want anything special just a mildly built engine that is reliable. also how can i rebuild the tbi is it something i can do or should i take it to somebody that knows what they are doing or get an aftermarket one.
    thanks

    Why rebuild it at all? Was it a ruinning combo when extracted? If it was, I'd drop it in as is without touching it. Unless you REALLY feel like spending $$$ on it! In that case, toss a good low end cam KIT in there and call it a day. I have a CompCams 11-206-3 cam kit... which makes LOTS OF TORQUE & HP... LOTS. /forums/images/icons/wink.gif

    If the engine has a lot of miles on it, just take it apart and have it checked by a machine shop, do a valve job as well as bearings and rings. Then go back all stock except for a "SMALL" cam change (call comp & crane and ask their tech guys) As for the TBI, I buy stuff from Turbo City and have been very happy... They have a lot of options for a TBI from minor to major.... Good Luck...

    therod is knocking so it needs a rebuild. i was going to bore it out a little mainly just to clean it up and put a decent cam in it and call it a day. i just did not want to do it and regret not not doing it another way.
    thanks
