BEST Chevy Vortec V8 SPARK PLUG GAP? Engine Will RUN GREAT!

The BEST spark plug gap to run on 1999-2007 Chevy Vortec V8 engines. I always use the smaller spark plug gap on Chevy Vortec V8 engines. These Chevy Silverado trucks run BEST with ACDelco Iridium spark plugs with a gap of .040". I only run Iridium spark plugs in these GMT800 Chevy trucks. ACDelco 41-162 or 41-110 work the best and have the best engine performance.
