I'm looking at a dyno on my Roush. It starts recording at about 2,700 RPM where the torque curve is almost straight up to 440 ft-lbs at 3,000 RPM and slowly drifts up to 460 ft-lbs at 4,000 RPM. From there it slowly declines as the RPM goes up to 6,500 RPM. At 6,500 RPM the torque is down to 350 ft-lbs. The peak STD HP is 448 at 6,200 RPM. Based on my curve your torque may be very close to your 527 torque number around 3,000 RPM. I wasn't the owner when the dyno was run.
