No start on rebuilt 360LA

Should not need the MSD 6A, disconnect that, and just connect your three wires to the distributor, 12v, coil negative, and ground. Make sure you are getting 12v to the distributor while cranking as well as key on.

And make sure you have bypassed/eliminated the ballast resistor- ready to runs need a solid 12v at all times; in crank, and run, as said by royslead.
