Most people don't understand the relationship between torque and horsepower.
Engine output is measured on a dyno. Dynos measure torque.
Horsepower is CALCULATED from the torque number using the formula HP=TorquexRPM/5252.
Horsepower owes it's existence to torque.
Horsepower is just way of representing high speed torque.
At 5252 RPM, horsepower=torque. Every time, no exceptions.
When torque goes up, horsepower goes up. At any RPM
Any engine that peaks below 5252 RPM will make more torque than horsepower.
Any engine that peaks above 5252 RPM will make more horsepower than torque.

I think you are oversimplifying things a bit. Sure at 5252 RPM hp = torque, but some of the 60's engines have significantly higher peak torque relative to peak horsepower. You also make it sound like a linear relationship between hp and torque. They are hp and torque curves, not lines. Where and over what range you get your peak numbers makes a big difference.
