Yes, but you have to remember that in the 60s, torque was rated in gross numbers also, so it was just as overrated as the horsepower number was.
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.
