Super Six 2bbl or Hyper-Pak 4bbl in 270 Dart w/225ci

Well the starting issue doesn’t really concern me too much because the guy was using a janky home made battery. I’ll be buying at least a minimum of 800 CCA and installing new battery cables. Also, according to the wiring diagrams I believe he may have had it wrong. He’s running the negative to the starter and then a wire from the switch to the starter. The wiring diagrams for the car show negative straight to the switch and then from the switch to the motor. So I think it maybe wired backwards from when he installed the solonoid incorrectly at least “a dozen times” according to the previous owner
