(from Ford Press Release) The
2005 Mustang V-6 is powered by a new 4.0-liter, 60-degree,
single-overhead-cam engine, replacing the 3.8-liter 90-degree pushrod
engine in the 2004 model. It’s inherently smoother and more compact,
provides more power and torque and incorporates many of the advanced
technologies used on the V-8.
The 200-horsepower, 235 foot-pound engine – gains of 7 horsepower and 10
foot-pounds – features low-profile heads, a composite intake manifold
and a sound quality tuned to match Mustang’s powerful image.
