Yeah, but it's a very good hauling machine. With 360 HP and 460
ft/lb
of torque, it'll move stuff. You just don't get that for free if
you
have to go gas instead of diesel.

-----------------------------------------

Ford's V10 is one of the few gasoline engines that has the torque
ratings of some similar sized diesels. It's too bad it developed
a
reputation for spitting out spark plugs.

Strip the threads out? Had a Honda SL-350 dirt bike that did that
on
both cylinders. Thanks for Heli-coil inserts!!

------------------------------------------------

That was Ford's fix for a while. The problem is that a Heli-coil
in
aluminum isn't any stronger than the original thread, so it would
sometimes happen again. Ford blamed shade tree mechanics, claiming
they were over-tightening the spark plugs when replacing and
stopped
doing warranty repairs.

The spark plugs don't need to be change but every 100,000 miles
these
days.



Helicoil in anything adds substantial surface area to the mechanical
surface of the threads, it's just math.

-----------------------------------------------------

True, but the material the heli-coil is installed in isn't any
stronger. A heli-coil is great for replacing stripped out threads
that need to be drilled out but it doesn't make anything any stronger.
