Do you have spark at all eight cylinders? I saw you mentioned the #1 plug, but how are the rest? Usually it’s easier to start with that to rule out anything upstream (cap, distributor, coil).
I had a crank/no start a few months ago. Fuel pressure was 60-psi. It had weak spark on #1, a little better on #3 and none at all on #2. I didn’t check the rest, but swapped on an extra distributor cap (Delco) that I had laying around and it fried right up. The defective one was some off brand that came with a Summit distributor that had probably less than 1,000 miles on it.
Like the poster in your reddit thread mentioned, they make a tester with an adjustable gap to gauge the strength of the spark.
