I think many people buying diesel trucks without turbos did not realize that diesel engines have less power then gas engines of equal sizes, and not more. That's why GM originally designed the 379 diesel (6.2 liter) to have equal power to the 305 gas engine. They are almost identical in horsepower and torque curves.
Ford-IH non-turbo 444 (7.3) is close to power and torque as a 351 gasser and that's what it should of been compared to.
7.3 non-turbo has 180 horse @ 3300 RPM and 345 lbs. torque @ 1400 RPM.
351 gasser has 210 horse @ 3800 RPM and 325 lbs. torque @ 2800 RPM.
Now, when the 7.3 turbo came out . . . 190 horse @ 3000 RPM and 395 lbs. torque @ 1400 RPM.
And the direct-injected 7.3 turbo Powerstroke . . 210 horse @ 3000 RPM and 425 lbs. torque @ 2000 RPM. That is for the first year, and power increased as time went on.
