More good stuff...

09-24-09: The long talked about big-block 6.2 liter engine from Ford
was unveiled today in Texas as part of the introduction of the
redesigned 2011 F-Series Super Duty Trucks. Ford enthusiasts from
truck owners to hot-rodders alike have been waiting to see what the
first all-new V8 engine family from Ford since 1991 would look like.
Well here it is.

The new 6.2 liter V8 will replace the Romeo 5.4 liter engine in the
truck line. The power will outpace the current 6.8 liter V-10. Ford
has stated that for 2011 the V-10 will remain an option for commercial
applications. An all new architecture, the 6.2 V8 engine features
single overhead-cams with variable valve timing and two-valves per
cylinder. Unique to the design of the heads is the accommodation of
two spark plugs per cylinder.

***** *=> seems like they are going backwards in Technology. ****

The engine will be available as the standard power plant for F-250 and
up Super Duty trucks and optional on the F-150 for the 2011 model
year. As it is a dedicated and purpose designed truck engine it is not
expected to show up in a new Mustang without being reworked to shave
weight from its stout iron block. Roush has however been experimenting
with a 7-liter version in their drag racing cars which hits 800hp and
has been bullet-proof so who knows what evil may come if SVT chooses
to play with the new engine series.

Making this engine particularly robust is the over square cylinders
which have a bore of 102mm and a short 95mm stroke. This arrangement
tends to lend itself to high performance and better revving
capabilities. The single overhead cams with variable timing use roller-
rockers to act upon the valves which are arranged in a true “hemi”
form. Anyone who builds engines knows this is best for breathing
capabilities.

Basic construction consists of a cast iron block has cross-bolted four-
bolt main bearing caps, aluminum heads, forged steel rods, cast
aluminum pistons, magnesium valve covers and a plastic intake
manifold. Compression ratio is a relatively high 9.8:1 and it can run
on any variation of pump gas from regular to E-85. Pretty slick huh?

Significant development work and computer-aided engineering optimized
the cylinder block for more efficient airflow in the crankcase as the
pistons move up and down in the bores, resulting in improved torque at
higher engine speeds. Piston-cooling jets squirt oil on the underside
of the pistons to keep the piston crowns cool under extreme operating
conditions. The cooling jets also allow for a higher compression ratio
for better engine efficiency and faster engine oil warm-up on cold
starts, also improving fuel economy.

The only details we don’t know yet are the horsepower ratings. Ford is
withholding that tidbit until later, but most rumors and leaked
reports put the power at just over 400 in naturally aspirated form.
Imagine what the SVT guys could do with a set of 4V heads, aluminum
block and some force feeding. Screech!
