Buy the real Holly!

This is a pretty simple device, buy Holley and only buy it once! Make sure the venturi assembly has backfire protection so they last longer. Choosing the right size is important, take the idle manifold vacuum reading and divide it in half. This is the main way to find out which power valve you need. If you look at power valves and know what they do, you probably already know this :)

Pros
  • Easy to use
Cons
  • Operating speed
