The Rev N Nator is a replacement MP style ECU that requires the magnetic pickup distributor to work, the Holley won't be able to control it unfortunately if you're looking to control timing from the Holley.
I'm researching this stuff myself, I already have a 6AL and Blaster II coil, was going to use the points output from the Holley to drive the MSD box. If I were you since you need to replace everything and already bought the Hyperspark distributor, I'd buy the matching Hyperspark CDI box and coil. You won't have a ballast resistor in line with the 12v feed to the coil anymore.
