CnP (coil near plug) for big blocks

Holley HP kit 550-501 is what I used with 66 lb/hour injectors. Makes 900 hp @ 7000 rpm on race gas. I originally tried to use the Holley dual sync distributor but it didn't fit with my Indy heads so I made my own cam sync unit. Here is a picture:

Andy,

What are you running for your cam sync? I have read about the 68 charger that ran the Jeep 4.0 L cam sync with an adapter (Mopar Action had an article but didn't give him credit). But this looks like something different? Trying to do research for a low deck.
