spark and no spark

Not sure what it proves, other than I have 12volt from the ignition switch.

yes, wire is off square terminal on relay. I though I was eliminating the starter while give everything else the same voltage when key is turned to start.

Battery in trunk with one hot wire up to starter. Battery is grounded to frame.
Engine has a 4G ground braided wire to the k member and the stock ground from fire wall to engine head.

Everything I have check while cranking motor, voltage has dropped
coil
ballast
starter relay-large top bolt
Battery drops to 10.5
distributor pickup gap is .006
white wire in pic from ground is grounding the FBO ecu
checked battery cables from post to wires and from post to frame for negative; no change.
