I don't feel tardy
today i had the oppurtunity to compare similar trucks, both '87-'91 style Super Duty (F450) dump trucks with 5 speed trannys. the 7.3 has 5.13 gears in back and i assume the 460 does as well, being a SD. i was driving the 7.3, running EMPTY, and my buddy was driving the 460 powered truck, with a load (at least 3 TONS) of dirt/clay. he was leading, i was following. we came to a hill, posted 9% for a half mile or so. i purposely fall back a little, expecting the loaded truck in front of me to slow down climbing the hill. he rockets up the hill, in 4th gear at 3000 rpm i later confirmed. i was in 5th with my foot to the floor and i was eating his dust. i couldnt catch up intil we passed the top of the hill. dont think downshifting would have done a lot for me as i was already running 2000 rpm at 45 mph. gotta love 5.13s.
the 7.3 i was driving has a brand new injection pump on it, installed and timed by me. having driven this truck many times, as well as my own 6.9, and ridden in numerous other IDI trucks, i can say that the truck i was driving is a strong running NA 7.3. i guess my point is that i was very impressed by the 460's power. it was blowing smoke, burns quite a bit of oil, and gets 6 mpg, but it sure run circles around the IDI. even the turbo IDIs i've ridden in would be hard pressed to run with the 460.
for now i'll still keep my 6.9 though. even at 60+ cents spread gas/diesel 6 mpg is tough to swallow.
