Getting parts ready for a new 440 Six Pack engine that will be finished shortly.

I need a distributor and plan to try a Firecore.

I plan to use the plug and play distributor and have a Rev N Nator ignition box.

So which distributor do I need, the one with the vacuum advance or the race one with no vacuum advance?

The 440 is going into a street car with occasional trip to the drag strip.

Any suggestions or experience?

Thanks

OK let's clarify a few things, the plug and play (ready to run) units have a CD ignition built into the base of the distributor.
If you want to run a revenator unit you need the standard mag pickup unit.I like the tall mechanical advance unit myself. I'm one of those guys that don't use a vacuum advance

Ah yes he must referring to the new connector design that uses the standard Mopar connector instead of the first gen units with an MSD style connector.
My mistake the "ready to run" was sometimes refereed to as a "plug and play" unit
