The 361 max RPM is 14,000, max torque is at 9500, and it's 4.6bhp. I don;t have the exact numbers for the 359.
According to the 2005 Stihl catalog (the latest catalog that my local dealer has) the MS361 has 4.4bhp @ 12.3 lbs and the MS361C has 4.4bhp @ 12.6 lbs. Neither are listed as having '4.6bhp".
Leave it to a Stihl dealer to fudge the numbers whenever they can. And being that you appear to have fudged the one number that I could actually check on, your other figures are now also suspect.
By comparison, according to the 2006 Husqvarna catalog the Husky 359 is listed at 3.9bhp @ 12.1 lbs. And the Husky 357XP is listed at 4.4bhp @ 12.1 lbs.
The power-to-weight champ in this class is the Husky 357XP.
According to the catalog the 357XP has "fast acceleration" and "high speed power". I take that to mean it's a higher reving saw than the 359, which is listed as a "power and torque" saw.
