Mallory HEI distributor

I recently purchased a Mallory HEI dis. model# 8548201c. I got it to replace my stock distributor on my '84 Ponitac Grand Prix , Chevy 305. I have a Holly Carb and was told I would need a earlier style dis. I called summit and they recommended this distributor cause I wanted to stay HEI. I knew that the connection to the ECS would be lost and I kinda wanted it to. Let me get to the point, I removed the old distributor making sure the rotor was pointing at the num. 1 spot and I removed it. The rotor spun during removal but it had to in order to release. I tried placing the mallory so that the rotor would be lined up the same facing num.1 ( the line I drew on the manifold) , but it wouldn't mesh so I spun the rotor until it meshed perfectly down into the block. I wired everything I could back up, but it wouldn't start. I was told after asking around that maybe I "180 out". Not sure what that meant but I decided to move the wires around on the cap keeping the same firing sequence 1,8,4,3,6,5,7,2. I just rotated them to different spots on the cap. It originally looked like this on the cap:

............................................6...5
.........................................3........ .7
.........................................4........ .2
............................................8...1
But the only way it would start is when I moved the #1 wire to the 2 spot and everything sequenctially (2 to 7, 7 to 5,... 8 to 1) . It started but wasn't working right had no power. I didn't change the sequence just the spots on the cap. I'm really not sure what I'm doing wrong so any help would really make my day. And if you need any more info I'll tell you whatever I can.

Thanks
