You couldn't possibly pay me enough to own a Toyota car or truck. I've never
liked them. As for my truck of choice, I would take the Silverado. Then
again, seeing how we build them, I may be biased ;-)

I did not say your Jeep was not more Jeep than new ones. I have been
around Jeeps since late 50's and when AMC bought them in early 70's it
was the best thing that ever happen to Jeep in modern times because
they refined the drivetrain and gave the Jeep a more stable foundation
and under AMC the highly sucessfull mini Cherokee was born in 84
(there was a full sized one that was discontinued in 83). AMC bulit
good sturdy motors that were never appreciated by many. Chyrsler is
running Jeep into the ground and the best thing that could happen to
Jeep today would be to get away from Chyrsler. Dated or not is was a
mistake to kill the sturdy proven Cherokee and replace it with the
Liberty. They should have kept Cherokee as a base entry vehicle and
bastardized the grand instead.
>I think GM is finally learning the lesson about quality and is turning

I do not think GM has learned anything yet really. Just look at a 2007
Chevy P/U as what appears to be a beefy bumper in front of each front
wheel is merely chome plated plastic that will fail with a mild impact
with anything much more than a emtpy paper bag when at speed (just
wait until they start busting them off in snow drifts. Rest assured
with each new model GM finds a way to built them cheaper because
labors costs is killing them. The new 6 speed auto (6L80) being used
in new HD P/U's with 6.0 takes about 65% less man hours (about 270
bucks less man hour wise) to assemble because it modular design can
be assembled by a robot but the bad thing about this design and
assemble is that there is no "drive" gear in it (it has no 1 to 1
ratio that can be selected) because of the componud modular design and
it remains to be seen hhow this will pan out in tim is HD usage.(it is
either in a underdrive or overdrive mode with no direct drive possible
as it compounds/selects different planetaries to get its six speeds
with no direct main shaft availble for 1 to 1 drive) The sturdy Ally
and the new Toyota 6 speed auto still have a 1 to 1 drive ratio

4 valve design has been arround for too long not to use. That is unless you
don't think the consumer deserves it.
Also, is the 4.2 L ford engine a 90 degree V6, Is that an indication of a
lower red line ?
The 4.6 for the Ford truck is the same pushrod 2-valve.
The mustang engines are still pushrod design.
Is there a Ford V8 with 4 valve design ? How about variable valve timing ?

Corvette V8 6.0 L 16 valve OHV 400hp-6000rpm 400ft-lbs-4400rpm
Tundra V8 5.7 L 32 valve DOHC 381hp-5600rpm 401ft-lbs-3600rpm
Lexus V8 4.6 L 32 valve DOHC 380hp-6400rpm 367ft-lbs-4100rpm
Similar numbers out of less displacement. This would suggest the Corvette
would benefit greatly from an updated valvetrain design.
According to the mustang engine specs .. all 3 engines have hydraulic
lifters hence not DOHC.
So add the 5.4 L to the list of the pushrod engines.

That's easy with pistons on both side of the rotor, more even, and
responsive pressure can be applied on more braking surface area without
having to float the caliper.
It also contributes to capacity for greater braking surface area.
I'd say there is NO hype in prefering 4 piston over 2.

Yep I'm well aware all manufacutrers have had issues with gasket recalls.
What about cruise control systems that burn your car and house down ?

According the info from the link provided above, the 4.0 L has a single
overhead cam, the 4.6 L has overhead valves (pushrods) and the 5.4 L has
double overhead cam.
It is possible for an overhead cam engine to use hydraulic lifters.
