No it is not. The 4.6L V-8 in the trucks is a 2 valve SOHC design.
No, the 4.0L V-6 in a Mustang is an SOHC design, The 4.6L is the three
valve SOHC design.
Currently none of the Ford V-8s have 4 valves. In the recent past
certain models got the DOHC 3.9L, 4.6L, and 5.4L V-8s, but Ford is
getting essentially the same horsepower from the 3 valve SOHC design,
so they aren't offering a 4 valve V-8 at the moment. Ford does offer
several 4 valve DOHC I-4s and V-6s. All the 3 valve engines have
variable valve timing, as do the DOHC engines.
Look under the hood of a Tundra, and then look under the hood of a
Corvette. Which engine takes up more space (the Tundra). Which engine
weighs more (the Tundra).
No true. You don't have to have push rods to have hydraulic lash
Spoken like a techno geek who thinks if race car has something it is
the best thing for a street car. The "pressure" applied is no
different if everything is working properly. With sliding calipers the
biggest problem is sticky sliders. With modern sliding calipers that
are properly maintained this isn't much of a problem. 4 piston caliper
don't suffer from sticky sliders (there are none), but they do suffer
from sticky pistons (been there) and you have twice as many seals to
leak. As far as I am concerned there is only one advantage to 4 piston
calipers - you can plumb the pistons in pairs to achieve true dual
circuit braking. I am not sure it Toyota is doing this - do you know?
I doubt it since they would have to have twice as many brake lines
running to the front of the truck.
No, this wrong.
The Tundra doesn't stop any better than competitive vehicles. If there
is no performance advantage, then it is hype.
Or sludged up engines that burn up your car? You should look at the
history of the cruise control deactivation switch recall. Initially
there were a very few vehicles from a clearly designed production
range that appeared to have a problem. Ford announced a recall for
those specific vehicles. Suddenly every sort of Ford truck built in
the last 15 years was accused of catching on fire. Fords were accused
of burring up that didn't even have the same style circuit. Sort of
like the Toyota sludge case don't you think?
