This Edelbrock #1902 AVS2 500 CFM 4-Barrel Carburetor is a strong upgrade option for Full Size Jeeps running an AMC V8 with a compatible square-bore intake manifold, such as the Edelbrock Performer Non-EGR intake.
The AVS2 series is designed for smooth street performance, improved throttle response, and consistent fuel delivery. The 500 CFM rating makes this carburetor well-suited for stock or mildly built AMC V8 engines where drivability, reliability, and clean throttle transition matter more than an oversized carburetor.
This carburetor uses Edelbrock’s AVS2 annular flow booster design to improve fuel atomization, especially at low RPM and part-throttle operation. That makes it a good match for heavy Full Size Jeeps that spend most of their time cruising, driving around town, trail riding, or pulling from lower engine speeds.
The lightweight aluminum body helps dissipate heat faster than heavier cast designs, reducing heat soak and improving consistency. The two-piece body design resists warping and allows internal tuning changes without removing the carburetor from the intake manifold.
This carburetor includes both timed vacuum and full manifold vacuum ports for ignition advance tuning and is factory calibrated for single-carb applications.

Important Fuel System Notes
Edelbrock carburetors are not designed for alcohol, race fuel, or E85. Use of alcohol-based fuel or E85 can damage the carburetor and may void the manufacturer warranty.
