For Model 2300, Model 4150, Model 4160, Model 4500 Holley Carburetors
Why use a power valve block off? If you have a dedicated race engine that never sees part throttle, but goes right from idle to full throttle you may see more consistency. The block off screws right in place of the existing power valve. Includes gasket.
  • Can offer more consistency on racing engines
  • Screws right in place of Holley power valve
  • Gasket included

Information:

Note: Main jetting will need to be increased 6 to 8 sizes when plug is used. Not recommended in street or street/strip applications that see any part throttle at all.
