1968 340 timing

Just to clarify;
Every custom plugwire kit I ever installed , has wires of various lengths in the box. Usually, if the D is installed per the factory way, then the wires all fit.
But if the D is installed in one of the "Seven" other positions, usually, no matter how you route the wires, #2 is gonna be too short.lol.
Even after you get the D in as recommended by the factory, It is still possible for the D to be out one tower, and the Vcan kissing the coil, or in some way too close to the radiator, making it impossible to set the power-timing. The Vcan needs to be backed up all the way to the firewall, then pulled forward slightly, until a reluctor-vane aligns with the pole-piece on the Pick-up. or the points just open. I do this with the crank positioned to 10* advanced. This makes an easy-start and fast enough idle, to get started.
After this I slam the rotor on and with a Sharpie,index the housing as to where the rotor is pointing. Then install the cap, and whatever tower is above the index mark I made, is the new #1 plugwire. The rest follow according to the firing order.
If the index mark falls between towers, yur in trouble, something is wrong.
Don't do what I did my first time. I pulled the D and moved the Intermediate shaft one tooth and slammed it all back together, with same results as before, just the rotor moved over to between two different towers. Crap said I; I musta made a mistake. So I did it again with same results. Crap said I; I musta made a mistake. Yes Olie, I moved the I-shaft a third time, with predictable results.
The point is this; the I-shaft has nothing to do with the rotor landing between towers.
If this happens to you;
and you have a Mopar Electronic Ignition system, then;
the reluctor is probable indexed wrong on the roll-pin,and will have to be re-indexed. If you look closely on the reluctor you will see two positions available, with arrows stamped as to their installed direction of rotation. These are supposed to make your rotor line up correctly. If yours still does not line up, then something else has to be moved; either the rotor or the cap.
But if you still have points, then you will have to check that your point gap is correct, and after that your correction points are again; moving the rotor or the cap. or the cam,lol
