Degreeing a Cam, or not.....

One last thing about this. Ignition timing. To sum up where we are. I verified that the Crankshaft 0* mark is at the top dead center with the piston. That did not change. I adjusted the camshaft 8* advanced to match the cam card. I re-assembled and left the ignition timing where it was. Now my question.

I did not change the crankshaft pulley, just re-installed it so my TDC did not change. So my timing marks on the crank should be accurate,,,,correct?
Finally, how would what I did affect ignition timing? I have not checked it and I will this weekend. I should have before starting it but I did not. The sniper controls the timing advance and I just need to set the initial timing.

It would seem to me that advancing the cam, I would also be advancing the timing since the distributor is driven from the camshaft. My brain is struggling with this one. I will check and post where I am at now this weekend but any advice welcomed.
