Thanks everyone for your all your input thus far. Greatly appreciated.

When I am finding tdc on comp stroke my thumb is being blown off the sparkplug hole on #1 cyl. Correct? As soon as that happens I then check the distributor. The rotor(little metal tab) is pointing almost directly at the drivers seat. Standing at the front of the motor it's pointing like 1 o'clock. Is that correct? So now i put my #1 plug wire in that spot on the distributor cap and follow the firing order clockwise. Also I noticed there is a groove/line on the harmonic balancer and that line is about 2" past the timing tab.

The timing tab is around the 2 o clock position and the line falls after the tab around the 3 o clock position. I dont know if that needs to at a certain spot.

I never pulled the distributor out. Just changed the wires. I don't know about previous owners but I havent removed it.
