    Since I'm gonna have to change my timing cover, I figure it's now or never with the cam. Besides the obvious stuff that has to come off to get the timing cover off, what parts will absolutely have to come off to change the cam? And are there any parts that alot of people take off, but don't necessarily have to come off? Thanks

    That pretty much covers it, and of course the water pump. dont forget to have new intake gaskets on hand when you are doing it.

    Also change the timing chain and gears while you're there.

    I just changed mine a few weeks ago, and this is all the stuff that had to come off of mine,

    Intake mainfold, and obviously everythng mounted to or thru the intake, ie carb, distributor, etc.

    valve covers, rocker arms

    oil pan

    Water pump, p/s pump, alt, smog pump

    balancer

    timing cover

    fuel pump

    now thats all just to get at the cam, to get it out i had to take off/out

    the radiator

    the a/c condensor, which required the removal of the grill

    the center grill support,

    and i think that was about it.

    it took me a couple days, but man it was well worth it. I had a flat lobe/destroyed lifter, but now she purrs like a kitten. /forums/images/icons/grin.gif /forums/images/icons/grin.gif

    If you change cams often, you might want to consider upgrading your lifters to roller ones; this way the intake manifold stays in place. Plus; I think; you get an increase in power.
