Look at this Distributor orientation..

If the engine already runs, and none of the wires are too short, then what more do you want, just drive it.

Yea, it fires right up, but there is a stumble. I'm hoping it's related to this.

As triple R already eloquently put it- It’s not

In a perfect world, the rotor would point directly at the plug tower at 25-30 degrees BTDC. That somewhat "centers" the rotor as the timing varies from maybe 5 to 55 degrees BTDC. I've always tried to make this work by a combo of tang position and plug wire position on cap. The spark will jump to the nearest cap contact so you don't really want tdc to be directly at your cap contact as that would put the 55 btdc too close to the #2 cap contact (the one prior to #1 firing). It will still work if you do line them up but I'm more comfortable having it somewhat centered.

Checked it again, and the Tang and Rotor are lined up properly according to the Service Manuel. Now I have to move on and check a few more things because there is a stumble (hesitation.)

Are the pick up leads black and white coming out? If so wrong pickup, They can be grey and black at times with a MP. It also looks like the tag starts with 369 which would be a MP distributor with a really fast curve that can make it stumble also.
