Now, Edelbrock engineers have taken a great carb and made it even better with the exciting Edelbrock Thunder Series AVS! Designed and calibrated to deliver optimum street performance in hundreds of applications, Edelbrock Thunder Series AVS carbs are undeniably the most innovative and dependable street performance carburetors available today. Thunder Series AVS carbs have outstanding features like the Qwik-Tune secondary air valve and share all the performance advantages of the popular Edelbrock Performer Series. Features like a sturdy 2-piece body, no power valves to blow for superior reliability and a design that's simple to tune to your needs make the Edelbrock AVS Thunder Series carburetors the best you can buy.

Optimize For Your Vehicle
Edelbrock's unique Qwik-Tune Adjustable Valve Secondary allows you to adjust the secondaries with simple tools... no springs required. Use a late opening for heavy vehicles with higher gears or an early opening for light vehicles with lower gears. Edelbrock carbs deliver optimum performance for whatever you drive.

Cool Custom Look
Edelbrock Thunder Series AVS carbs have a CNC-machined and profiled front face for a smooth clean look. Distinctive black hardware delivers a totally custom appearance. Looks as hot as they perform!

Available For Off-Road
Designed specifically to stand up to the tough 4x4 environment, these Thunder Series AVS carbs include spring loaded needles and seats for consistent fuel supply over rough terrain. The side-mounted fuel chambers are less likely to flood while climbing hills... no need for extended vent tubes. 650 cfm size is ideal for most small-block V8s.

Proven Performance
These carburetors have the same great features as our proven and dependable Performer Series line such as: float levels set at the factory so adjustments are rarely needed for "bolt on and run" performance; 2-step metering rods for independent tuning of cruise and power circuits; change jets, adjust floats or replace needles and seats without draining fuel. Of course, expert technical support is provided with all Edelbrock products.

Absolutely the Best Performing "Street Performance" Carburetor Ever to be Offered
What makes the Thunder AVS the best Street Performance Carburetor available? Newly designed primary and secondary booster clusters offer the most accurate and up to date calibration available of today's blended fuels and octane levels. The Thunder Series' unique AVS feature allows for limitless calibration of the secondary circuit with simple hand tools while on your vehicle. It's quick. It's simple. It's effective. Counterweighted secondary carburetors utilize a heavy, non-adjustable "counterweight" that relies solely on the velocity of the air coming through the secondary venturis to roll open the secondary air door. Under certain conditions, a delay or stumble can occur when transitioning between the primary and secondary circuit at Wide Open Throttle (WOT). This is due to the velocity not being able to roll the air door open fast enough. This condition is virtually eliminated with the AVS feature
