Dominator EFI ECU and distributor

I am contemplating doing an EFI set up on a slant six and I am looking for the best way of doing so such that I have the EFI talking to the distributor. Have any of you checked out this system from Holley?

The sales pitch indicates that it may work with a stock electronic ignition system, "Custom settings can be configured to allow for use with many other applications". Any ideas if a Mopar electronic ignition would work with this? If not, any ideas of an aftermarket distributor that might work?

I was thinking about a similar set up as is in this article, but, without the 13.5-1 compression!!

As for an intake, I was thinking about using an Offenhauser rather than a Clifford, but, maybe the Clifford headers.

Thanks for the input!
