quick question now !!!! HELP!

Small block Chevy - These engines have used three different timing pointer locations. Pre '69 engines have the TDC mark 2° to the left of the keyway centerline. The '69 to '85 dampers have the TDC mark 10° to the left of the keyway centerline. The 1986 to 1991/1992 have the TDC mark 40° to the left of the timing mark. All of our SB Chevy dampers, as well as all other aftermarket dampers, use the 10° TDC position. Our 6.75" diameter models have two TDC marks, one that is 10° and one that is 40° to the left of the timing mark. If you have a pre '69 vehicle you can use one of the aftermarket bolt-on timing pointers to align correctly with the timing marks on our dampers.

i don't remember where the keyway points at TDC. i'm assuming it points at 12 oclock and if so then your pointer is in the 40 deg position. so if you have the 6.75 balancer then it should be marked for the 40 deg. if you have a larger diameter then your balancer isn't marked for the location of your pointer

how do you figure? according to the company his balancer is marked for a 10 deg pointer. 3 oclock would be 90 degrees, his pointer is at 2 oclock so that would be well above 10 degrees where it states his balancer is marked
