TDC, top dead center is when the number 1 piston is at the top of the cylinder. 8 degrees before TDC is where you set the distributor so that is when the spark plug fires. You use a timing light to set the distributor. There is a timing mark on the crankshaft pulley and a series of marks on the timing chain cover that will show where 8 degrees before is at. The timing mark on the pulley is a small notch in the edge of the pulley closest to the timing cover.
