    Will that work with the stock computer? Well with a Hypertech program I guess... Damn, I really want more out of this motor! :)

    yes, a lot of the secnd gen guys are running cams on the stock tune, since the mootor has a MAF its able to calcualte the fuel trim a little better then speed density motors

    so in short it will run on the stock tune, but you can get more out of the motor with a custom tune for the cam

    Could I get a part number for the cam, I've checked Jegs, and can't find a 4.3 cam anywhere.

    And they are available from Summit Racing. Use the search on their page, and you should come up with several options.
