What did the torque power curve look like? More precisely, at what rpm did it start at before peaking at 4400? High stalls create issues on chassis dynos. In most engines the difference in torque peak rpm and horsepower peak rpm is around 1500rpm+/- a few hundred. Because horsepower is a mathematical derivitive of torque. If the HP peak is accurrate on the chassis dyno (much more possible than the torque peak due to the convertor being pretty much constantly locked at that rpm) the torque peak should be closer to 3800. If your convertor stalls at 4, the dyno load will confuse it and the indicated torque is usually kind of weird.. Like it may start at the highest level and drop, or it may be a basic flat line until it rises a hair and drops off on the graph. If the torque number was right, the HP peak should be closer to 6K. I can't see a cam with [email protected] peaking that high with a set of RPMs on it. Treat these engines like deisels in terms of gearing and stall speed and they love it...lol.
