No start on rebuilt 360LA

Do you have a spare points dizzy? Or a standard mopar ecu ? I'd hook up something as simple as possible to get the engine broke in then you can trouble shoot your msd issues! Is it backfiring through the carb while cranking?
Nothing spare that would be easy to hook up, all the factory wires were cut and/or removed. That’s why I went the MSD route.

**Update 2**
Now getting fire through top of the carb consistently every time we attempt a start.
