Bradley,
Both motors are rated at or about 185/385 specs. Both pull about the same from my experience, owning both. What I do find, is the 7.3 pulls from a start quicker, but later in rpms the 6.5 goes faster due tot he turbo. The 6.5 also pulls better at elevations above about 3-4000', again, due to the turbo.
The 7.3 will overheat less, the 6.5 unless it has the post 97 dual t-stat, higher flow water pump has some overheat issues. After changing out my 96 to the post 97 mods, my few overheat issues became a thing of the past.
