Carburetors

Carburetors

Performance and replacement carburetors improve fuel metering, throttle response, and power output on engines that rely on carbureted fuel delivery. Whether you are rebuilding a classic, swapping for more airflow, or restoring an original engine, choosing the right carburetor cfm rating and jetting is essential for proper tuning. Popular Upgrades The most popular choices include double-pumper four-barrel carburetors for high-RPM performance, vacuum secondary four-barrels for street driving, two-barrel carburetors for economy and mild performance, and rebuild kits for restoring OEM units. Brands like Holley, Edelbrock, and Demon Carburetion lead the category for both street and track applications. Do you carry carburetors for older or classic vehicles? Yes. We stock replacement carburetors and rebuild kits for a wide range of classic cars, muscle cars, and older trucks. Options are available for Holley 4150 and 4160 series, Edelbrock Performer, and other popular applications for Amer...

Edelbrock

Edelbrock

Edelbrock is one of the most storied names in American performance parts, founded in 1938 and now part of the Edelbrock Group with over 130 years of combined brand heritage, producing intake manifolds, carburetors, camshafts, cylinder heads, superchargers, and complete crate engines for domestic V8 and performance applications. The brand's Victor Jr. and RPM Air-Gap intake manifolds remain benchmarks for small block and big block Chevy, Ford, and Mopar V8 performance, while the E-Force supercharger system has become a preferred positive-displacement blower option for Mustang, Camaro, and Corvette builds that demand both power and factory-fit quality. Edelbrock's reach extends from restoration-correct carburetors for classic muscle cars to modern EFI fuel injection systems and fully assembled crate engines that provide a reliable, matched-component solution for engine replacements and hot rod builds. Builders and restorers across generations choose Edelbrock because its catalog spans...

Fuel Delivery

Fuel Delivery

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...
