i can only imagine how slow it would be with the 4.0.
Yep, it's bad, but not as bad as you might think. As you know though, the 2F and 3F designs (overstroked for one) keep the torque curve rather steep and peaks very early in the RPM range vs. the torque apex of the overbored 4.5 at IIRC ~3200rpm?
FJ803FE on the ExPo here (who unfortunately is quite an idle user) and I are out with our rigs often. Driving his FJ80 you can certainly tell that there is a more immediate feel of power to rock climbing and the truck due to to the 3F's torque rise is able to power over some obstacles that take the 4.5 a little more of the skinny pedal to do. Put both rigs on an open flat sand road though and there's no comparison.
The absolute torque numbers aren't there, but the `quality' of the torque in it's RPM range is truly outstanding on the old 3F, plus being effectively a destroked 2F can pull a few more rotations to yield some higher HP (granted not much).
The 4.5 is still an awesome engine though...
Oh, I
should clarify the PTO winch is really just
any PTO winch that you could put up there, because you can mate an H41/H42/H55f easily and thus have access to the various tcases with PTO gears.
