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

That tells me nothing. What have you checked?

1....That the HEI module is FOR CERTAIN flat against the sink, with some thermal compound. Those modules have a locating pin out the bottom, and either you must break off the pin, or have an appropriate clearance hole in the sink
2....Make absolutely certain that the screws are actually tightening on the module, and not bottoming in the holes.
3, I would forget factory wiring. Hook up everything except power and then "hot wire" 12V battery direct to coil

I've done over 5 of these now. One was in a Toyota 20R that I swapped into an old Cletrac Crawler. One was my own car, and one was my "emergency ignition" system, and I've helped with others These are easy. You just have to be careful.

How about the distributor. What is it's history? Are you confident it works? Where'd it come from, etc? And did you do the clearance with a feeler and check the AC output?
