1-8-4-3-6-5-7-2 Standing in front of car looking at the engine, Cyl. 1 is on the right, Cyl. 2 is on the left, then they count towards the rear. So on the right side is 1-3-5-7, on the left is 2-4-6-8.

    Been there, done that, in the earlier years. One thing good to know for future. When your wondering which cylinder is # 1, on any V-6 or V-8 engine, stand beside front of engine, (fender) look across front & whatever cylinder head sticks out the farthest towards front of vehicle, that is # 1.on that side.

    Set your timing marks at TDC on compression stroke & distributor rotor should be pointing at #1 wire terminal on cap.

    As mentioned above. Your rotor under cap will be pointing at #1 if your at "top Dead Center" on compression stroke. When your sure you've found #1, next one going clockwise beside #1 is # 8, then next one clockwise is # 4, then 3, 6, 5 ,7 ,2. Have a look at how far the wire has to go, from cap to spark plug to determine the best suited length.
    Does that help?

Firing order on a 305 on the cap. Got the wires all messed up...


This method is good for the firing order on all chevy small block v8 engines from 265 cubic inches to 400 cubic inches. This would include 265, 283, 305, 327, 350, 400 cu. in. chevy small block v8 engines.

Let's cover some safety concerns first. If you try to troubleshoot a mixed up firing order with the engine running, you could be in for a serious shock,.. literally. You can do it, with certain precautions, but you really don't need to check the firing order with the engine running. You definitely don't want to try checking the firing order if you are wearing any kind of pacemaker or sensitive electromechanical prosthesis. The voltage coming out of the ignition coil is in the thousands. Common sense dictates that you wouldn't stick a knife in an electrical outlet, so you wouldn't want to take chances with being shocked by the electrical discharge from your classic chevy's ignition coil either. See the diagram:


5d6424a.png

The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.

On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.

Additional details HERE.

Hope helps (remmeber rated this).
