It has timing chain and gears. NO belt.
I could be wrong, but I have a Vortec 350 in a GMC truck and I think the computer handles the ignition timing. If your talking about valve timing I would assume there are marks on the timing gears like the days of old, but I haven't torn the timing cover off of mine yet.
Yes.
10 horsepower or less
line the timing mark from the crankshaft sprocket up with the camshaft sprocket and tada!
The life expectancy of a timing chain on a 1999 454 Vortec engine is 5 to 10 years. The exact time depends on how often the vehicle is driven.
