Like everyone else, I agree with the distributor being 180 out. I used to do that almost evey time until I started insuring that #1 was on the compression stroke when installing the dist.
Here's how I do it now: I turn the motor over with a socket wrench on the crank snout bolt and all the plugs pulled out. (You can also do this with a remote start button.) As the timing mark comes up to the indicator, I put a finger over the #1 spark plug hole. If I feel air being forced out past my finger, it's on the compression stroke. If not, I keep turning it over until I feel the compression.
With the timing mark lined up to TDC on the indicator, I position the distributor so that the rotor points to the location of the #1 spark plug wire. Then I stab the distributor into mesh with the gear on the cam. It will probably be necessary to align the oil pump gear with a long screwdriver to where it will mesh with the slot on the end of the dist. It might take a few tries, but it'll get there eventually. Then you can fire it up and set the timing with a light.
