Your logic makes sense, but it is because there are 2 extra power strokes per cycle. Torque is measured as work/cycle.. horsepower is work/time, a v8 will do more work per cycle than a v6 of equivalent mass.. the extra mass associated with v8s usually is the reason why they don't rev as high as smaller engines and don't make as much horsepower.
