383 won't start. It cranks, I have spark & fuel - could it be the battery

I would never spin an engine for 30 straight seconds. I can only imagine how much your starter hates you.

It hurts to imagine.
Reminds me of the day I wired up plugs on on small block distributor and the brain was following big block rotation.
Heard a few backfires that day.
Poor starter..
