Man I wish I was closer to you so I could lend a hand. I say start from scratch. Hook the 'pink' HEI power wire right to the battery positive. Too many other things to go wrong using the car's ignition circuit. Rig your test harness so every spark plug wire is grounded to the engine block. Spark plugs removed. Hook up the timing light inductive pickup to the #1 spark plug wire. Power clips go to the battery, red + and black -. Crank the engine. It should spin rapidly and every time #1 fires the timing light should flash. Let me know what happens.
