    I Have A 91 Jimmy With 187,000 Miles And An Burning Some Oil And Was Wondering, How Big Can I Bore The Block And What Ratio Cam Cam I Use With The Stock Heads And Stock Tbi System For The Most Power Upgrade While Still Using The Stock Tbi? I Dont Want To Spend A Lot Of Money On This Because I Am Only Going To Only Have This Engine In It For A Year Until I Can Afford A New Crate Motor.

    I can imagine your on a low budget, you spent all your money on capital letters.:D

    Seriously though, if your getting a crate in a year, I would throw some Restore in it and thicker oil for now. Or even a decent used engine to get you by.

    Just do a standard 30 over bore.
    For the cam just use a mild computer frendly cam. Comp Cams make some good computer frendly cams for around $100-120. Crane also makes some good CompU cams but they will cost more.
    Keep your Durations at .050 under 214* and Lobe seperation around 112*. Should give you power up to 5K rpm and work fine with your stock chip and heads. You can call eithr Crane or Comp cams they will recomend a cam # for your needs.
