My question too is what's the point in 7K? I use my Roush 427SR for track days, but see no point in anything over 6200rpm. The Roush dyno sheet shows max hp at 5700 rpm and max torque at 4400 rpm. Plenty of power shifting at 6200. Beyond that power drops off anyway. You want high reving engines, get a 4 cylinder with a really wild cam and a power band 8-10K rpm.
