i have a 97 4x4 f350 with the 7.3 , i lucked into it and got it for $400. it didin't run , or have a bed on it and the cab is all banged up, but i finally got it running and on the road, i dont know how modified it is, but i know the 7.3 in it is not anything like the
one on the manual and there's lots of chrome and 2 turbos, it gets 20-22 on the highway and 19-20 in city driving, , and yes that's accurate , its dual exhaust to.
