Factory Service Manual does not list different coils for Slant 6 versus V8. The 1.5 ohm coil and a 0.6 Ballast Resistor is the best match to the Factory Electronic Ignition set up.
I don't recall where I read it.....Unfortunately. I think it was another car forum. I was trying to figure out how to match one of my coils to the 1.5 ohm resister that I happened to have....I ended up using the coil that totalled between 2.3 and 3 ohms. This is on my run stand.
