A number of sites say the 3.7L peaks at 4600rpm. A more thorough search than trying to remember off the top of my head returns the 2800rpm specification as well, but seems to be tied to the 3.5L. And that may be true, as the 3.7L might just build off of that number on it's way to 4600rpm, making for a pretty flat torqe curve. Unlikely though, considering how much harder the engine pulls over 4000rpm. Of course, one website said the HP and torque values were EACH less than 150!! I will have to do some more digging later.
