I bought a 6.3/4" harmonic Balancer cover #66517BK for the 84 L69 305 H/O. The problem is the TDC timing marks don`t line up. With a New timing chain and gears installed straight up, Dots lined up. The Balancers timing mark lines up with the 0 on the timing tab, Both I assume are stock. So when I install the cover the mark on the cover don`t line up with the balancer or the timing tab. With the Motor at #1 TDC the marks on the balancer and timing tap lined up, So the balancer didn`t slip, Right. If the balancer spun the marks wouldn`t line u, Right. When I lay the Balancer on the bench and line up the balancer bolts holes and crank key with the cover bolt hole hole and the notch the mark are off. So what`s the problem ?
