    0411 5.3 cam tuning.

    Anybody have any tips for getting a base tune close before it goes in?
    This will be a stock 2001 5.3 with .617/.624 lift,231/239 duration on 113 lsa.
    Also has a 75mm TB,which I don't believe is stock. Zero emissions,manual trans for th400 with no VSS.
    I know alot of it can be calculated to get it close,but best place to start?

    I'm looking for stock TB size,from there I figure I will calculate the percentage increase over stock and scale the airflow tables accordingly?
    I always referred back to my cam tuning thread and pm's from mondax,ed wright gave some excellent advice in there.

    What's the best way to pencil whip this thing before we start it up so it's close?
