1965-1966 Vintage Shelby Mustang GT350 Twin Paxton Supercharger Kit (dual carb)

Paradise Wheels 65 66 Mustang Twin Supercharger 2 carb

This Twin Paxton Supercharger kit is for a Ford 289 or 302 in a 1965-1966 Mustang, without power steering, using a two 4 bbl Holley carbs with “Cobra” bonnets on an inline 2×4 intake manifold (manifold not included) for a 2-Stage (first blower blows pressure into second blower for boost) step up. The kit is patterned after the original 427 Cobra Twin Paxton set-up that Shelby made in 1965.


There are many options and configurations. To get a kit properly customized for your specific application, please use the Product Enquiry form below to send me details of your application and ask any questions you may have about placing your order.

  • This system can potentially make 100 to 150 extra HP on a 289 or 302 depending on the engine combination.
  • The McCulloch and Paxton blowers use 8 to 10 oz. of  Ford type “FA” automatic transmission oil.
  • The Paxton ball drive blowers are a silent type blower with a fiction drive so it will be hard to turn. (20-30 in. lbs. turn torque)
  • These blowers can run hot, so an oil cooler option is recommended (250.00)
