Holley is the legendary American carburetor and fuel-injection brand — over 100 years of induction history. From the iconic 4150 four-barrel to today's Sniper EFI conversions, Holley remains the choice for muscle car restorations, Pro Mod, and gasser builds.
The power valve is a critical component in your Holley carburetor, responsible for providing the extra fuel needed during high-load, low-vacuum conditions. The Holley 10.5 power valve is a standard flow, single-stage unit designed to open when engine vacuum drops below 10.5 inches. This ensures your engine receives the necessary fuel enrichment to prevent lean conditions during acceleration and heavy load.
A properly functioning power valve is essential for both driveability and performance. If your engine hesitates or stumbles under load, your power valve may be the culprit. This 10.5-rated valve provides a reliable solution for maintaining the correct air-fuel ratio, ensuring smooth transitions and consistent power delivery. Built to Holley's exacting standards, this unit offers the longevity and performance you expect from a leader in fuel system technology. Keep your engine running strong and responsive with high-quality components. Explore our full range of carburetor maintenance parts and fuel system upgrades available at GGCRACING.
