Default Distributor orientation L98

How do I know where #1 is on the cap so that I can get the distributor orientation correct?

If you still have the old cap and wires, then just put them back in the same spot. Did you pull or otherwise not have the original distributor in place? From memory, the distributor should go in with what would previously been the vacuum advance mechanism on the passenger side facing about the #6 cylinder, and the #1 wire would be on the terminal roughly pointing toward the #1 cylinder. With electronic control instead of vacuum advance, the big HEI distributor body should still have the cutout where the vacuum advance would have been.

I found this pic on this site. Numbers on the coil does not make sense. Why would #1 wrap around like that and #2 be low on the odd side.

You. Found a textbook install. Perfect orientation.

Don't feel. Bad. Most GM "modern" master techs.
Oblivious how to install a HEI distributor. Even worse.
No clue. How to set timing.

Attached a factory HEI wire retainer / factory wire orientation. Molded within.
I shaded this ring. The shaded area lines up perfectly with the caps connector block.

#8 in my pic looks way off from the lower pic but the wire retainer pic looks like it matches the lower pic.
