    retarding cam

    we just bought a new stock class computer from hulk. and in the directions it says to fully retard the cam for the best results.

    i see that a couple of people have the stock class computer on here, did you have to retard the cam? and if you did did you "fully" retard it? just wondering before we install it.

    we have a stock cam in it for now.

    Retarding the cam gives you more top end (higher rpm) horsepower.
    Advancing the cam gives you more low end horsepower. First thing one should do is degree the cam to make sure when its "stright up and down"
    that its where it should be. Then start playing with advancing or retarding the cam. This can be done with off set keys.

    Retard the cam for more upper rpm power and advance the initial timing in the ECU to get the low rpm power should work very well, did it couple of times on some old street cars with good stock cams. I asked about cam timing the cam a few days ago, it doesn't appear to use a key or bushing but has a slot that a dowel in the cam can move in.

    And how do you suggest we do that? The ECU is not adjustable/programmable.

    the cam sprocket is slotted for adjustment.
    The stock race ecu has more timing.
    Frasier at PPG should be an expert with this.

    he is talking about the timing gear. they have a slot in it so you can move the timing.

    yep, the slot adjusts cam timing. NOT ignition timing!
