WHY?
Push rod engines have been around a LONG time. Toyota even agrees as
they built more than a few. (take a look under the Tundra V8s hood)

The production Tundra's 4.7 and 5.7 liter V8's are both DOHC designs. The
NASCAR Craftsman Series "Tundras" use pushrod engines ;-)
AFAIK, Toyota does not sell any pushrod engines in North America any more.
People have probably spent millions of hours debating the benefits of
pushrods vs OHC engines, and IMHO, each style has benefits over the other in
certain applications.

The main advantage to a pushrod engine is packaging. I believe that
was one of the reasons given for GM for sticking with a pushrod design
for their newest small-block V-8s; they needed them to fit under the
low hoodline of a Corvette.

Of course, you could've just written it down in a text document and saved it
rather than posted it, assuming the actual purpose was to not lose it.

Joey, you should take a hint from Jeff Strickland. He's
much more polite and together than you.

Clarity of purpose is a good thing. Try it sometime.

Re: Some details of the 2AZ-FE engine
I think it was Buick. Had an Aluminium engine in something like '62.
V8, I think it was 300 ci. I did a brake job on one of those cars once
and really liked driving it. So when I gave it back to the girl that
owneed it I tried to explain that it was of utmost concern that this
car NEVER be over heated. Always check coolant and have a GOOD
radiatoer, fan belt, water pump, etc....One year later she was trying
to sell it to me because "We think it's only the head gasket". Right.
Aluminium warps really good.

The engine was 215 cubic inches and had cast iron liners. GM sold the
tooling to British Leyland and they continued to produce it for years.
I think Ford finally stopped producing it when they bought Land Rover
(but according to wikipedia, it is still in production at third
party). Oldsmobile sold a turbocharged version. It was sold in various
Buick, Oldsmobile, and Pontiac intermediate sized cars (included the
Tempest that used a transaxle with IRS).

Re: Some details of the 2AZ-FE engine
The 2AZ-FE has a variant 2AZ-FXE for hybrid cars.
By the way, the supercharged 2AZ-FE's found on some of the Scion tC,
are there other modifications on the engine or just added the super
charger? Would you be able to fit a supercharger on a camry, rav4 or
highlander?

Re: Some details of the 2AZ-FE engine
Hee hee hee. 2AZFE "an advanced powerplant?" that's a good one.
Checkout the Audi FSI 2.0T for an advanced design with a flat torque
curve from 2000-5000 RPMs.
