I wasn't aware of numbers on the 70-72 gauges, and didn't know bigblocks were part of the blazer line.
I can tell you my 72 blazer oil pressure gauge does coincide with a hand held mechanical gauge I had T'd into just for a comparison. And when the factory gauge was pegged it matched very close to the 60 lbs. mark on my handheld.

My 79 pickup with a factory 454 doesn't have an 80lbs. gauge either. Neither did the 77 bigblock I had before that. They were also all 60 lbs. gauges,,,with actual numbers on the gauge in those years.
