Leave well enough alone.
Can a sludged engine run perfectly fine?

If its the 350, I doubt even sludge can make it croak. My friends Tow-Truck buddy has a late 80's Chevy 350 tow truck and it busted a head gasket while towing a car from PA. Truck didn't even flinch one bit.
But if you wanted to clean it there are a few options, some recommend ARx(never used it), I used MMO in my Xterra and it worked for me(bit cleaner inside), using a heavy detergent oil(Pennzoil YB/PP or your choice of oil). Or GUMout/Regane?

Short of tearing it down and vating every part in cleaner that would blister rhino skin nothing will really remove it.
Sludged engines seem to run hotter than normal.
But sure, many run just fine in light duty.
Don't expect maximum power, efficiency, or life from them, though.

Replace a quart of oil with Marvel Mystery Oil for a couple of runs, then consider AutoRX or Rislone...

1992? I assume high miles? At this point keep on keepin' on. I also assume this things doesn't owe you anything. If it starts making noise , turn up the volume of your favorite rock or country station.
Yes and reincarnating old threads seems to be a hobby for some.
