Timing Jumping Around

Just found this video. I am using the 440 Source bronze intermediate shaft like he showed in the video compared to the Milodon. Also, when I pull off the distributor cap I'm not sure how much I should be able to twist the rotor. Mine with the 440 Source shaft moves quite a bit. Edit: Duh, that is just moving the springs. Pulled the shaft out and there is a little play where the dist shaft engages the intermed shaft.
