When you are starting from scratch, it really doesn't matter which post on the cap is #1 - if you have it set up as you do, put in the distributor and wherever the rotor is pointing, THAT is #1. Wire clockwise from there, 1,8,4,3,6,5,7,2. For the sake of convenience, I use the post that is just left of center (driver's side) at the front of the cap as #1. I'm pretty sure the factory did it that way, and it really makes sense if your plug wires are cut to length and routed as such. I like to shine a light in the dist hole and make sure the slot on the oil pump drive shaft is in line with where I want the rotor to point so that the distributor completely seats.
If you are converting from your old points dist, make sure you are using a keyed 12 volt power source to the coil. Your old wiring to your points dist used a resistor wire and only delivers around 8 or 9 volts to the coil...not a good set-up with HEI.
One final note...the cylinders on the driver's side, front to back are 1,3,5,7 and on the pass side front to back are 2,4,6,8.
