My engine has developed a tick. It speeds up and slows down with engine RPMs. I checked for exhuast leaks, none. So I took it to the shop. They put a stethescope on it and found it loudest at the fuel pump. They also suggested I change my oil. After the oil change, its still there. What do you think it is, and how can I fix it?
its a 4bbl 289 w/headers

Take the fuel pump off and look at it. While it's off stick a screw driver in the hole and see if the fuel pump eccentric is tight.------------------

Probably your fuel pump, my brand new holley fuel pump had a broken spring in it and it make a ticking sound that I though was a valvetrain problem at first. I would definitely pull the pump and check both it and the eccentric.------------------

Do I need to drain the oil to take out the fuel pump? Or do I just unbolt it and pull it out? What would I do if the eccentric is loose?

You dont have to drain the oil,unless it need to be changed any ways.If the eccentric is loose the only way I know to tighten it.Is to remove the timing cover.
Maybe someone else knows of another way.------------------

No, you don't have to drain the oil. To check the eccentric just stick your finger in the hole the fuel pump arm goes in, way up at the top you should feel a round metal piece, if it wiggles your eccentric is loose, if it doesn't it is fine.------------------
