==How to find number one== 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. [[Image:Hei_firing_diagram_GM.jpg]] If all else fails try this. Remove the #1 spark plug. Remove the distributor cap. Put your finger on the spark plug hole that you just removed and turn the engine over slowly. Do this until the compression stroke comes up , you will feel air pressure at this point on your finger. Look at the timing indicator located on your timing chain cover. You should see a line scribed in the lower crankshaft pulley, line this up in the indicator pointing to 0 or TDC. You now have Top dead center. Look at the direction that your rotor is facing. It will point to #1 on your distributor cap. The wire that plugs into this hole in the cap is now #1. Connect the other end to the spark plug on the driver's side front. [[Category:Engine]]
