A 1995 Chevy Van with a 454 engine will have a spark plug gap of .060 inches. A difference of .005 (give or take) should not affect the engine's starting capabilities, however.
The spark plug gap on 1977 Chevy truck 454 should be set at .045 inches. Spark plugs are preset at the factory and should need no adjustments prior to being installed.

Spark plugs are a cheap and quick fix if one goes out. The cost to replace one on a 454 chevy engine however can differ depending in the spark plug brand.
