That is a pretty old truck, could be a loose piston and connecting rod, if so it is the kiss of death. You can try switching to high grade synthetic oil to see if it helps, but that engine may be on it's way out. Open engine compartment when engine is running, can you identify if the noise is coming from top end or bottom end? If bottom end, you will need to be doing some engine work or look for a new ride soon.

Oh yeah I forgot, it happened to me once in a old Chevy, I paid for the shop to bore it out and get all new stuff, and after I got it back it lasted about 6 months before throwing a rod again and finally killed it for good. If you really really love your truck, consider a new engine or a remanu'ed one with warranty. But if I was you, I'd just get a another truck. Until then, don't push the pedal to the floor. There is an off chance it could be carbon buildup, you can try running Kreen that stuff will loosen any sludge or varnish, and then trying some synthetic oil. Even if this helps, there would still likely be play in the cylinder, which means you are at the end of engine life anyhow. Don't do anything stupid like removing the wire to that cylinder, you will create a bigger problem with unburnt fuel then worrying about when the rod is going to go. good luck

if a good shop completely redoes your engine it will last just as long.
