I was getting a little pinging on my '81, so I decreased the timing advance from the stock 6 degrees to somewhere around 4-5 degrees BTDC. I was curious as to how much advance is ideal for my vehicle. Also, would switching spark plugs enable me to run more advance?
I have limited "feel" when it comes to timing the factors that control what I set my timing at. After I decreased the advance, I felt like the car was a little less "peppy", if that makes any sense (but the pinging went away I believe). Do spark plugs affect timing at all?
Currently, I have a 383, stock heads (CR ~9.5:1), 270H Comp Cam, stock intake, carb, distributor, and ECM. I did richen up the carb at WOT by switching secondary rods/hanger. Hooker sidepipes will be on probably next weekend.
Thanks everyone. Your insight is greatly appreciated.
