Timing out because of wrong Damper?

I have a '85-'89 stock 350 carbureted small block where I'm having trouble checking the timing. The motor runs smoothly and doesn't stumble, but lacks power (I think). When I set up the timing light I run into this problem. At idle speed, distributor vacuum disconnected I cannot see the timing mark lining up with the pointer. If the vacuum is not disconnected there is no difference. I have an variable timing light and I turn the dial until the mark on the damper comes in line with "0". The timing light now reads 40 degrees. What gives? Do I have the wrong damper on the motor or has it spun enough to make this difference? The timing tab is about the 2 oclock position. And if it is the wrong damper how do I know what the replacement should be?

My 86 Camaro´s original 305 had the timing pointer at the twelve o clock position, had to look straight down behind the water pump to see it.
I replaced the damper and unknowingly installed a "two o clock" damper.

Best bet is to get number one piston to TDC, distributor cap off to watch rotor point to number one terminal, and see where your timing mark is damper/timing pointer.
I did that then remarked the "wrong" damper TDC.
