What Is the Firing Order on a 350 Chevy Engine?
The firing order of all small-block Chevy engines, including the 350, is 1-8-4-3-6-5-7-2. The rotor under the distributor turns in a clockwise direction. General Motors numbers V8 cylinders in an alternating sequence with the number one cylinder at the front of the engine on the driver's side and the number two cylinder in the front passenger side location, according to BoxWrench.
Chevy small-block engines include several different sizes, with the greatest difference in the cylinder bore. Chevy's installation of its first 265-cubic-inch small-block engine in the 1955 Bel Air began an era in the automotive industry covering over 40 years, with this design finding use in every General Motors product line other than the Saturn.

The Chevy 350 powers commercial vehicles and boats. It holds the distinction as the most widely used of all small-block engines.
