According to my owner's manual you should be 3 degrees before TDC for the Z24 petrol engine. If you are 7 degrees further advanced then ping away.

Have an 83 720 4x4 w/Z24 developed same problem all of a sudden. starts and revs up fine but put it in gear and has a really bad miss and knocking. did compression test and 3/4 cyl,had 50lbs. pulled the head and found cyl.3/4 head gasket blew between them.Apparantly found on internet that this was a common problem with these.Hope this helps someone.

i had that problem but not as bad. if you don't have the proper OEM spark plugs the engine will never run right. Make sure your plugs are the NKG plugs designed for that engine and make sure you put the intake ones on the intake side and the exhaust ones on the exhaust side. Secondly, i would double check that ignition timing, i have a 1986.5 hard body truck with the same engine and my timing is 5 degrees before top dead center. i am surprised you set it at 10 degrees. but i live in california so perhaps it may be different due to emission requirments.
