Designed for stock 289-302 Ford Engines. 1969 and earlier models require the use of crank spacer (p/n 90683).


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.
