go google and type in-- firing order for chev 305 v8 engine--- there will be pages showing the firing order, and direction of rotation

18436572 That's been the order since the late 50's, :) You also can look on the intake manifold it's on there too,

Firing order for a 305 is 1-8-4-3-6-5-7-2. The distributor turns counter clockwise and #1 should be the 5 o'clock position looking down at the top of the distributor.

The one on top beside the carb on the driver side. is for on the intake is for temp gage.

how many cylinders ,stupid question i know but as i have never seen one ,but i can give you the firing orders -153624 is the most common on 6 cylinder engines or 143625

Wow, a reply about an Australian based engine. I'm thinking since there is no reply that he just may have a US based engine just posted the wrong size. in which case this might help.
Here is a website with the American Version of Chevy info

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:




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.

try autozone.com or you can buy a hains book for around 12-14 dollars at any auto parts store.

The correct firing order is 18436572. If you need the correct cylinder locations they are as follows:
Drivers side from the front 1 3 5 7
Passenger side from the front 2 4 6 8
