The ultimate ïZZÍ crate engine package
Chevrolet PerformanceÍs all-new ZZ5 350 uses new-casting Fast Burn
cylinder heads equipped with LS-style beehive valve springs for greater
high-rpm performance. ItÍs rated at 400 horsepower _ more than any
Small-Block engine ever offered in a production Chevrolet muscle car
or Corvette!
The new, lightweight aluminum cylinder head casting is based onthe
proven Fast Burn design, with large intake runners and 2.00/1.55-inch
valves. New beehive-style valve springs enable greater high-rpm
performance and durability. They allow the ZZ5 to rev higher to make
the most of every cubic inch of air drawn through it.
