    Scrape the crud off the intake infront of the carb/throttle body. GM usualy cast that into the intake.

    well there is always the last resort method. you can put all the plugs in with no wires, the pick a wire plug it into the distributer on what you think could be # 1. the plug the other end of the wire onto #1 spark plug(the one closest to the fron of the vehicle) crank and see if it fires, if it does use some masking tape and a pen to mark it as #1. if it dosnt fire move the wire to #2 and crank. repeat the process till you figure them all out. once you think you have them all in the right spot pull each wire off one at a time with the motor running(use the insulated pliars) and see if the idel slows down at all.if it dosnt then you are all set. if not then you have 2 or more mixed up.

    i hope that made sence. and sorry about the level i dumbed it down to, dont mean to insult you, just trying to explan it as non-complicated as possible.

    BTW when are we going surfing?

    Here are the cylinder locations on your motor.

    Back
    -------
    |5***6|
    |3***4|
    |1***2|
    -------
    front

    The firing order is 1-2-3-4-5-6

    Here is your dist. cap-

    ****3*4***
    ***2***5**
    ****1*6***

    The #1 is the one closest to cylinder #5. I made the diagram to look like you were looking at it from the front of the truck. The little stars are just placeholders so that the diagrams look right.

    Hope this helps!
