HEI 8 pin module

Ok, after fighting with the ignition system I think I found the problem. I static timed the engine and aligned a point on the reluctor with the point on the pickup and with rotor pointed to #1. Something I happened to notice is that the rotor was not actually pointed at the #1 cap tower...it was off by quite a bit. I pulled the distributor and was looking at how the reluctor aligning pin was in relation to the rotor and compared it to another distributor. The reluctor pin was in a different location compared to the old distributor thus causing what I think is a big rotor phasing problem. I'm not sure as the distributor I was comparing to is a duel pickup type probably from a truck.

Would someone be able to post a picture of a known good stock distributor showing the location of the reluctor pin groove and the rotor locating groove?

Thanks!

When you say "off a bit" what do you mean. The rotor when the reluctor is triggering will be more like "corner to corner" with the rotor and cap contacts. This is because of vacuum advance. As the vacuum advance moves, the rotor contact will advance more andmore "into" the center of the cap contact.

Google "rotor phasing." You have several possibilities
1.. Rotor phasing is just fine and you are imagining
2...You have the trigger wires reversed regardless of what color/ diagrams say
3...There is actually something wrong AKA reluctor made incorrectly, wrong slot, worn/ damaged distributor, whatever.

There is only one way to know for sure and that is to check "rotor phasing" as shown in videos on google
