    Vortec and cam tunes

    I started a swap on my 87 tbi truck cam is going to be 214/224 .443/.465 112. I have a basic vortec tune found on this site flashed to a chip, think this will allow the engine to run with this setup?

    I think it should run but likely run rich, especially at idle.

    Unless you have a set of vortec heads, it will suck. The timing tables will be all wrong

    Then it will actually run fair. It will take a tune to wake up though. Not a lot of lift, but enough duration you may need to bump idle.
