UPDATE !! AUG 1, 2017
302, MS3X, BATCHFIRE, HALL DIZZY, 32-1 CRANK TRIGGER WHEEL + SENSOR, MSD6AL2

EVERYTHING IS WIRED CORRECTLY FOR FUEL ONLY, EXCEPT MAYBE:
-MSD BOX- GREY WIRE SAYS TACH OUTPUT SO THAT IS TO RPM GAUGE AND BLUE/WHITE WIRE TRIGGER IS CONNECTED TO GREEN/ORANGE TACH WIRE FROM DB37 PLUG (correct me if that is wrong).
-MALLORY UNILITE DISTRIBUTOR has RED, BLACK AND SHIELD WIRE, IT IS MY UNDERSTANDING I WILL NOT BE NEEDING IT FOR TIMING AND IT CAN BE USED USING RED AND BLACK WIRE AND TYING OFF SHIELD WIRE (correct me if I am wrong).

* I ran I/O test mode with injectors and heard and felt the clicking but couldn't verify if it was correct for the batch fire sequence. I am going to say that it is good considering I have been okay thus far. I am going to store in a few minutes during my lunch and for purchase of 5 more feet of fuel plumbing and a few fittings to finally prime and start this beast. SO I CAN LOG AND SHARE AND HEAR WHAT YALL HAVE TO SAY !!
