Ultra XP C/T Carburetor 750CFM

The Ultra XP C/T Carburetor 750CFM from HOLLEY is engineered for serious street and strip performance on modern and classic muscle cars alike. Built for enthusiasts who demand precise fuel delivery and bolt-on reliability, this carburetor eliminates the guesswork of tuning while delivering consistent power across the RPM band. Whether you're upgrading a freshly built engine or optimizing an existing combination, the 750 CFM rating makes this unit ideal for mid-range displacement engines and street/strip applications that don't require maximum airflow capacity.

The Ultra XP design incorporates Holley's proven vacuum secondary technology, which meters fuel based on actual engine demand rather than fixed metering rods alone. The 750 CFM specification balances throttle response for street driving with sufficient flow for moderate performance builds, typically supporting naturally aspirated engines in the 350–400 cubic-inch range. Dual inlet fuel ports accommodate both front and rear carburetor feed configurations, giving you flexibility in fuel system plumbing, while the compact 12.6-inch width allows fitment in tight engine bays. Holley's C/T (Conventional/Teapot) mounting flange ensures compatibility with standard four-barrel manifolds and adapters across multiple platforms.

Mechanics and engine builders favor this carburetor for street machines, bracket racing platforms, and restoration projects where tuning flexibility and proven reliability matter most. The 750 CFM capacity works best on engines with moderate cam profiles and stock-to-mild compression ratios; oversized engines or high-RPM applications may benefit from larger displacement models. Installation is straightforward on any vehicle running a conventional intake manifold and mechanical linkage setup. At 9.25 pounds, the Ultra XP C/T carries minimal weight penalty, making it ideal for performance-focused builds where every pound counts.
