I haven't seen the torque curve for the 5.0, but the same topic about the 6.2 got a lot of discussion in the SD forum. Peak tq is 4,500 and the stroke is much shorter than the 5.4/6.8 and guys were worried it wouldn't have any low end power because of that, but the dyno runs we have seen on it show it still making great low end tq. I assumed they would do the same with the 5.0, but I may be wrong.
