    Hey I was just playing with an engine program I have and was wondering what I should degree the cam at on a 350?
    It seems like a 5dg RETARD gives good power, but would it work?

    Been awhile but I think it is 4deg retard for more top end power and 4 deg adv for better low rpm grunt. Generally, best bet is straight up. Most aftermarket double roller timing sets are made so you can do 0, 4+ or 4- at the crank sproket.

    I just lined the marks up on the two spoikets. Worked well for me. I guess if I was building a fast car and not a truck i would take the time to degree the cam, but on a truck, its not that big of a deal.

    When all else fails... Check the blinker fluid.

    TB, Just install it straight up. It isn't worth playing around with on a daily driver IMO. This is really something for the guys who shellout for the 2 piece timing covers and have access to a dyno and/or drag stip. The changes generally are realtively small on stock and only mildly modified stuff.

    If you have the tools go ahead and degree it. You could be off a tooth when you line up the marks. Either way I'd just try and install it straight up.
