Set timing, hei mod

I found the original magnum coil in the garage. I guess that one would work. Can I connect tach signal on positive on coil like normal too?

Magnum Coil should work good.

Believe you need to connect your tachometer on the negative side (out going side) of the e-coil.

Just like the simpler earlier Points style systems where the tach signal wire goes on the negative side of the coil.

Best to leave that off to start with until you get it started up and running good with the e-coil first. One less thing to go wrong.

Up and running good, then hook up the tach.

Guess you probably know that you need to have your vacuum advance plugged while setting the timing.
Something like 12° Before Top Dead Center .
