The timing is different for each application, four barrel, 2barrel,California emissions. If you do not have the decal which is under the hood,then get it close with a vacuum Gage, as you move the distributor, you'll see the Gage climb, continuing in the same direction,the Gage will start dropping,then reverse till the Gage moves up.If your trying to stop it from pinging,on acceleration,use a higher octane fuel.
