HEI Conversion Done still not starting
First thing I'd try is to reverse the leads at the distributor connector. You can also check this with a timing light while cranking, if you have an old cap. Drill/ saw/ break the cap enough that you can see inside at the no1 tower and use the light to illuminate the hole. You should see by the light flash where the rotor is at the time of the spark. If in doubt, reverse the dist. pickup leads and see where it moves.
(This is known as "rotor phasing" and you can Google it. When you reverse the pickup, the AC wave coming out of the pickup triggers the HEI at a different point in time, thus offsetting the spark time from where the rotor is pointing)
Other than that, is the cam drive in good shape? Distributor drive gear OK? Timing correct?
How long has it been sitting/ how old is the fuel? Tried starting fluid? Any pops through the carb, tries to fire at all? How do the plugs look?
Also, ANY doubt about spark, your coil + and HEI + are now the same terminal. Make sure BOTH the dark blue "ignition run" and the brown "bypass" wire are tied together at that point. You can also "make double sure" by hotwiring with a clip lead from a battery connection directly to the coil+
I'm fairly certain this diagram is correct. NOTE which HEI terminal the male distributor connector is wired to
