Time is perhaps more important than miles, in the life of a timing belt. Seven years is the maximum life of the timing belt, recommended by most manufacturers. For instance, even if the engine has only 30,000 miles, but is seven years of age, the belt should be replaced.
Most dealers recommend changing the timing belt every 90,000 miles. Depending on driving habits and conditions the belt may last longer. I have heard of belts lasting 180,000 miles! The first gen LS's (1990-1994) have a non-interface engine, so if the timing belt breaks it's not going to damage the engine. If it breaks you'll just be stranded.
