Why would a 1995 GMC 350 make a tapping sound when cold that gets louder when warm?

If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do

When a hub bearing is broken it will create a rattling sound as the wheels spin. The after a car accelerates the louder the hub bearings will sound.

Sounds like a locked up FAN CLUTCH if its a front noise OR a bad MUFFLER-can't tell by the description. *From the description I would be more inclined to believe the catalytic converter needs to be replaced.
