Hei conversion from pints need help... what am I doing wrong.

As 67Dart273 says, the HEI module needs +12 V supply (B). If you have a ballast, you tap that on the upstream side of the ballast (not at coil+, which averages ~8 V). Best to toss the ballast and use an e-core coil. Even easier is a GM 8-pin HEI module and its coil and factory cable which connects the two so no fuss (1985-95 V-8 trucks). That loses the cute "under distributor" mount, but not bad since that sits in a grub-zone on a slant.

To insure you have the polarity of the two wires from the Mopar pickup to the HEI module correct, remove the distributor cap, clip the HV coil output wire to engine ground and clamp a timing light pickup over it. Flash it at the reluctor as you crank. It should flash when the teeth align with the pickup. If flashing in-between, you have polarity reversed and timing will be erratic. If hard to crank, you could remove the distributor and spin it by hand. Insure the pickup wires are short and twist them. Keep away from spark wires or you might get "positive feedback", like holding a microphone near a speaker. Also, the HEI module's body must have a good ground to work.
