GM has had different timing mark designs on both the timing and balance shaft chains. Independent of GM’s designs, Cloyes has designated the timing marks as shown in the illustrations to the right. With all designs the unique timing mark is aligned with the intake balance shade sprocket timing mark and intake cam sprocket timing mark.
