I don't know on that one. Dad had a 97 Triton Light Duty F-250 (7 lug). It had the 5.4l in it, and it was tight with the 5.4 in there, both front to back, and side to side. Also, they only have a "small" gasser radiator in them with no option for a bigger radiator, if it would actually fit, don't know if you could keep it cool. I don't think the triton even offered the V-10 because i don't think it would fit. So going from a small block that is tight to a big block 7.3 probably isn't going to fit. The 7.3 is somewhat tight in the 99+ SuperDuties..... and that engine compartment was designed to fit the 7.3. I know this isn't on the list, but the 6.0 is even worse for size. I am 6'4" and 350lbs..... that is one of the reasons I had Ron replace the ICP Sensor..... I can't physically get my hand into the location it is on the early 6.0.
