HEI Conversion Question and Holley 2280 Lingering Issue

I've already got one of Henry's coils on the truck. Guess I left that out. The current ignition setup has been on the truck for three years now. The old ballast resistor went into the shitcan about two days after I got it along with the coil and ECU ignition module which had left a nice stain of potting material down the firewall.

I did check the reluctor gap earlier today and it was >.010" on the one I checked. .010" was the smallest brass feeler gauge I have, so I snugged it up with a .006" steel one per the factory manual. Didn't make an appreciable difference.
