It is quite possible the car made 415 tq, but at different (much lower likely) RPM.
The "reduced" HP and TQ equation is...
HP = (TQ x RPM) / 5,252
So, you can say the value of HP and TQ is always equal at 5,252 RPM. And the value of HP is always lower than TQ below 5,252 RPM and higher than TQ above 5,252 RPM.
