I have a mild 440 with mopar performance distributer,MSD 6AL and blaster coil. Is it nessasary to run a ballast resistor with this set up?

You don't need the ballast with the 6AL. On the other hand, it doesn't hurt anything as the coil is not getting voltage from the ballast, with the 6AL. The 6AL just uses that lead as an on/off switch and gets its power straight from the battery.

Superb, check your MSD manual. In bold letters it tells you that the only connection to your coil will be the black and orange wires directly from the 6A. No other connections to the coil are allowed. With a capacitative
discharge ignition, around 500 volts is being supplied by the 6A to the coil. The 6A is responsible for the amount of power being delivered to your coil. A CD coil is therefore recommended, in order to take the best advantage of the 6A ignition. The ballast is used with your stock solid state amplifier to limit the coil current. If you are triggering from the stock electronic amplifier, (MSD white trigger wire) the ballast can be bypassed. If triggering directly from a mag pickup in the distributor, (MSD black and purple) the ballast will not be connected to anything. Do NOT connect it to the coil.

As said, you don't use it. That's the fine print. You don't use it, not that you remove it.
If you wire the msd unit as per the instructions, the factory ballst resistor is no longer part of the coil primary system and not being used.
Leave it in, so when you go back to a regular system, it wll easy to wire.
Leaving the ballast in will not effect performance in any way.
