Trouble starting up 67 GTS Dart After winter storage.

You said closed; but didn't say on compression stroke. Split overlap looks closed......... but isn't; and you didn't mention crank position at all.
So to re-iterate
it's #1 piston at TDC-compression*. Then drop D in with rotor pointing to front of intake bolt on the drivers side. Them back up crank to the 10* advance mark. Then push Vcan all the way back to the firewall, and then pull towards rad until the nearest Reluctor-vane lines up with the center protrusion on the pole-piece.. Then make a mark on the outside of the D where the rotor is pointing. Then install cap and make sure there is a tower directly above your mark. Make that your #1 tower. Finally, wire the cap 18436572 in CW direction.
If the rotor is not pointing to the front intake bolt, then pull the D out, and re-index the I-drive, until it does.Be sure that when you reinstall the I-drive that it engages the oil-pump, and that the drive gear drops all the way back down beside the cam, with a satisfying "thunk". Sometimes you have to rotate the crank a few degrees one way or the other to make this happen. Just put the crank back immediately after it drops in, so you don't forget. Repeat as often as may be required to get the rotor pointed at or near to that front bolt with the #1 piston at TDC-compression*.
(*) #1TDC-compression, may not be same as the balancer mark ;if you find this out, then it's your job to make it so.
Good luck
BTW.
Since I built my engine in 1999, I have never pulled the D to prime it in spring, even tho it has sat there in the cold since no later than October 10th.
My 750DP has no choke blade. I throw a tablespoon of fresh 2-stoke mixed gas down each of the primaries;then get in,open the throttles about half way and start cranking. It usually takes about 8 to 10 seconds before the AFR is right to support combustion, during which time the mechanical fuel-pump is filling the bowls, and depending on the ambient temp, I may be pumping the pedal.
8 seconds at 350 rpm would be 47 revolutions; 10 seconds at 300rpm would be 50 revolutions.
This engine currently has over 100,000 miles on it.My HV oilpump seems to be doing it's job.
Jus saying
again, it's not a small block. It's a B engine 383.
