OK, so back to the timing...how do you go about actually setting the timing? Do you have to loosen a bolt on the distributor? Can this be done with the cap still on it? How do you read the light? The mechanic I took the truck to originally said that I could not set the timing on my truck because the computer sets it...meaning that the distributor could not move. Not sure of the validity of that statement, but I figured that most of the 351W's were pretty much the same. Im just not knowledgeable about cars to set the timing on my own without a little guidance. I dont know what to move and what to aim the light at or read the light for that fact. LOL

Reason: Needed more info.
Right, I get that...but the lingo is difficult for me to comprehend. Heck, I dont even know where the harmonic balancer is. LOL From the diagram, it looks as if it is attached to the distributor...which does not move on my truck.
Incorrect. The distributor does move on your truck. The base timing is set by removing the SPOUT connector, then moving the distributor. You use a timing light to verify the distributor is properly set. Once you do that, put the SPOUT back in. The computer does control the timing with that SPOUT plugged in.
Your mechanic is not helping you any by making misstatements like they have. Find another mechanic who knows something and/or buy a repair manual to help you understand what needs to be done.
Here is another link to a technical writeup for upgrading the ignition components and bumping the timing up from factory specifications. There are some more photos and captions to help you out: ignition upgrade and timing bump
