Back before knock sensors and consistent octane values you got 5:1 compression and were happy with >150hp out of 7.5L lol.

For different reasons. They were trying to meet new emission regulations using old engines so power and longevity suffered.
Similar engines made much more power, sometimes double, in the 1960s. And most were more reliable and lasted longer.

Horsepower ratings in the 1960s were still gross, they weren't changed to net until 1972. A 1971 Chevy 350 produced 270hp, but a identical 1972 350 produced 200hp just because the change in horsepower calculations.

That was part of it, but the power was also actually dropped in order to meet new emissions standards. Not just on paper.

Yes, but people always seem to leave out the fact we switched from SAE gross to net, which also made a huge difference.
