Working on electronic ignition conversion for HP273 dual point distributors
Here's a pic of the Pertronix 1385LS installed in my (1967 273) IBS 4013 cast iron dual point distributor. Seems like it fits to me... with rotor and cap on, the shaft spins freely, no problem.
I did find slight interference between the vac adv arm and the adv plate. You can see it in the picture. I will be relieving just a bit of the arm in that area for clearance.
Also, there is a felt washer, a metal washer, and what I first thought was a home made wire clip for attaching the vac adv to the plate. I am now thinking that is an actual clip. Does anyone recognize it, or have seen them before?
On disassembly, the felt washer was on the bottom, with the metal washer above, then the vac adv arm, with the retaining "clip" on top. Does that sound right?
I had to loosen and rotate the silver ground wire to where it looked best to me, and the red / black wires had to be pulled through the grommet for what seemed to me to be the right length. Hopefully those wire won't rub on anything and cause a problem.
There is no adjustment on the pick up, so it must be fine? Also, there is a white sticker on the face of pick up... not sure what to think of that? In the pic you see one sticker on top, but there is one on the sensor surface as well. I may remove that one later.
Upon verification that the unit does fit, and all seems well, I have ordered a 40001 (chrome) coil, and 708180 stock looking plug wires.
I have been advised by Pertronix to bypass the ballast resistor at this point, which is fine by me. One less weak link to worry about! I will leave it in place to keep the stock look.
