It sure sounds like a newer smaller engine is screaming when it is putting out it's top
power, But you gotta remember they are aluminum, thinner walls, Sound penetrates
the walls much easier, tuned intake and less flow restricted exhaust, and often
multi-valves per cylinder. Many of those older engines had a top rpm limited
by the moving mass of the parts, and poor breathing capability of the intake and
exhaust. A lot of the older engines made a lot of noise, very cool sounding noise,
but from the factory, poor performers compared to today...

And I think 4 valves per cylinder was the biggest thing.... Can you imagine the old
302 v8 with 4 valves per cylinder...HOT ! ! !
