I think that is a bit strong. The Pierce specs claimed max 160 and 175 bhp occurring at 3400 rpm which I calculate at 247 and 271 ft lbs respectively. The maximum torque would normally occur at a lower RPM than max bhp. Based on test dyno data of a reasonably similar engine of the same era I would expect max torque to peak somewhere in the vicinity of 1800 rpm at about 275 and 305 ft lbs respectively. Many years ago I recall someone found some dyno data of a Pierce and it was published in the PASB, but I think it was an Eight and I haven’t been able to find it again since. I remember it was a bad copy and very hard to read!
