for Small Block Ford
  Weiand 142 & 144 Series Supercharger  

Want instant, full-time POWER for your Mustang or Ford powered street machine? Weiand’s Pro-Street supercharger kits are engineered to give you 25% to 40% more power every time you hit the gas while maintaining outstanding street-ability!

Engineered to fit the 289/302 fords (or stroker versions based on the 8.200 deck height), this kit will transform your mellow street motor into a monster with incredible torque and top end horsepower. It is designed to work in conjunction with stock type accessory drives and is available in satin or polished finishes.

This 174 low-profile blower features PTFE tipped rotor s for tight rotor to case tolerances and only requires a small cowl induction hood for most applications.

All Weiand 174 blowers feature 100% new CNC machined parts (no remanufactured components), including new thick-wall cases & rotors to eliminate high-RPM flex and provide maximum reliability. All superchargers are built in Weiand’s state-of-the-art manufacturing cell and each supercharger is 100% boost tested to help you squeeze out maximum power & efficiency.
