| The place was Columbus
Ohio in 1992 at the Nationals. Indy
introduced the 440-1 head and manifold
combination that soon became the most
popular power for the 440 Wedge engine.
With the newly designed heart shaped
combustion chamber, it's still the best
selling package at Indy, transforming
power deprived combinations into serious
street/strip machines. The best use
of the 440-1 is a 451" to 540" bracket
engine. This head makes the engine perfect
for the serious bracket racer...650HP
to 850HP engines with a single carburetor
that produces great torque and low shift
points. Purchase a complete kit for
correct engineered compatability.
