Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

The whole TDC is now 180 off is a red flag. Either the distributor was 180 before but the wires were rerouted so the firing order was correct…or the distributor is now 180 degrees off. If the plug wires didn’t change when the distributor position did it won’t run. When you look in the cavity that the distributor sits, the dizzy drive gear that the distributor fits in looks symmetrical but is not. So, just to get it all correct set TDC using the flywheel, then make sure the distributor drive gear is positioned correctly (you can easily find pics online). Then install the distributor (again, the ‘key’ and gear are offset to one side so if the distributor isn’t engaging check that the key on the dizzy is positioned correctly to engage the dizzy drive gear in the engine). Wire up the dizzy, install plug wires to correct cylinders. Car should start. Then you can adjust advance via the app (if you have Bluetooth version) or choose your program if you have the old type 123.
