The 0-60 mph time for a 2010 Chevy Silverado 1500 with the 5.3L engine varies depending on several factors including transmission type (automatic or manual), rear-end gearing, and the vehicle's overall condition and load.
However, a generally accepted range is 7.0 to 8.0 seconds. You'll find some sources claiming slightly faster or slower times, but this range is a reasonable estimate.
