its so hard to say how much i spent on the 7.3 ....i'd say over 4-5 years of it i spent at least 100k ..that includes trying stuff, moving on, trying other stuff, all the work, time , breakage... but for the actual total ..i'd say about 25k ...tranny, turbo, nos,injectors, built motor, lockers, traction bars, etc... that was to make 728 ... to do it with the 6.4 under 2k. its sickening.
Yup was the same for my F350 vs 5.9 - just smarty in dodge put down 60 hp more ( then all mods on 7.3)
-then forthe same money put into the 7.3- the dodge had 200hp more and better drivability
-Now I put a good chunk of change into the 5.9...... but should be a fun MONSTER.
