The firing order on a SBC 350 V8 is...1-8-4-3-6-5-7-2. The cylinders are numbered 1, 3, 5, and 7 on the driver's side and 2, 4, 6 and 8 on the passenger side. If you are planning to replace your ignition wires always do 1 wire at a time. The # 1 spark plug is the driver's side front of the engine. Trace that ignition wire to the distributor cap and you now have #1. The wires run clockwise on the distributor cap. So the next wire in line would be #8 , the next will be #4 and so on.. If you already removed the wires and seem lost you can either look in a Chilton's manual and/or see the firing order in the picture diagram.

*Look at the rotor. It will point to #1 on your distributor cap. The wire that plugs into this terminal in the cap can be called #1. Connect the other end to the spark plug on the driver's side front. Continue by following the direction of rotation to attach the remainder of the plug wires following the firing order.
