According to Ward's Auto, an experimental 6.2-liter, direct-injection
V8 producing upward of 500 hp could be factored into the next
Chevrolet Camaro equation. The engine would coincide with the Gen V
version of the small-block V8, based on GM's existing all-aluminum Gen
IV (L92), which powers the Cadillac Escalade, GMC Yukon Denali and
Hummer H2. According to Wards, the prototype powerplant resides in the
engine bay of an Escalade being tested at GM's proving grounds. One GM
engineer says it's developing "well north" of 450 horsepower, a 10
percent increase in low-end torque and three percent to six percent
better fuel economy. That from the new injection system, which
features eight high-pressure injectors that squirt fuel directly into
the side of the combustion chamber at 2,250 pounds per square inch.

Makes you wonder how much horsepower direct injection would give the 7-
liter that powers the current Z06 Corvette.  And this makes me eager
to see how much Ford's upcoming 6+-liter Hurricane/Boss V8 puts
out.
