Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
The Best "Street Performance" Carburetor
Edelbrock engineers have made a great carburetor even better. The new and exciting Thunder Series AVS carbs are designed and calibrated to deliver optimum street performance in hundreds of applications--they are undeniably the most innovative and dependable street performance carburetors available today. AVS stands for Adjustable Valve Secondary, which means just that--you have the ability to adjust the secondaries with simple tools (no springs required).
You can use a late opening for heavy vehicles with higher gears or an early opening for light vehicles with lower gears. For unmatched street performance, combine these carburetors with Edelbrock Performer, Performer Air-Gap, Performer EPS, Performer RPM, RPM Air-Gap, or Torker II manifold and camshaft combinations.

Edelbrock Thunder Series AVS Carburetors deliver a refined street performance experience with groundbreaking adjustability and smooth throttle response. The AVS ("Adjustable Valve Secondary") design allows users to fine-tune secondary opening timing with simple tools—no springs required—so you can dial it in for heavy vehicles or lighter builds with ease.
At the heart of the Thunder Series are the same advantages found in Edelbrock’s Performer lineup: factory-set float levels for minimal maintenance, two-step metering rods for independent tuning of cruise and power circuits, and the ability to service jets, floats, and needles without draining fuel or removing the carburetor. Their two-piece body design features no gaskets below the fuel bowl level—significantly reducing the risk of leaks.
Additional premium touches include a CNC-machined front face for a sleek, custom look and spring-loaded needles and seats for reliable fuel supply in off-road or rough-terrain environments—perfect for 4x4 and performance builds. Available in 500, 650, and 800 CFM variants with both manual and electric choke configurations, these carburetors are as versatile as they are high-performing.
Whether you're upgrading for enhanced driveability, cleaner aesthetics, or off-road endurance, the 650 carburetor edelbrock option offers a balanced profile for most street and weekend-driving applications. The edelbrock thunder series carburetor blends innovation with practicality—making tuning and maintenance a breeze. As a whole, the edelbrock thunder series represents the ultimate street-ready carb upgrade: adjustable, reliable, and engineered for performance.
With improved throttle feel, minimal upkeep, and dependable construction, the Thunder Series AVS is a smart, long-term investment for anyone looking to elevate their ride.
