Small Block Ford – 174 Series

174 Pro-Street Supercharger Kit

PART #: 77-174FSBP-1

UPC #: 090127545935

Emission Control Number 3

No centrifugal blower can compete with the Weiand 174 Pro Street small block Ford motor for making serious horsepower and torque. This Roots–type blower provides the flattest torque curve which translates directly into mid–range and top–end power. You''ll need more hood height than stock. However, if you want to be fast, it''s a small price to pay. Plus it''ll look like you''re loaded for bear.
