The Edelbrock AVS2 Series #1905 is a satin-finished carburetor with manual choke that is designed and calibrated for optimum street performance in engines that require 650 CFM of air-fuel flow. The AVS2 is a perfect four-barrel replacement or upgrade that features annular flow primary boosters with a new calibration for improved off-idle and cruising performance. The annular flow booster design delivers improved fuel atomization to eliminate flat spots that may be encountered as the carburetor transitions from idle to full throttle. Each annular flow booster features eight equally spaced orifices to improve fuel metering from idle to the main circuit. The improved flow metering makes this carburetor ideal for use with a wide variety of small- and big-block engines with either dual- or single-plane intake manifolds. The Edelbrock AVS2 #1905 includes both timed and full vacuum ports for ignition advance. It comes with: .101 primary and.098 secondary metering jets, .070 x .037 metering rods - orange, (5" Hg) step-up spring. Use our Carburetor Stud Kits #8008 or #8024 if needed. Match with a variety of manifolds that include Edelbrock Performer, Performer EPS, RPM Air-Gap, Performer RPM, Torker II or other brands of similar design. For a black-finished AVS2, order part #19053.

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
