Lock in race-inspired performance without breaking the bank with ATM’s Gas XRSC Series 650 CFM carburetor. Finished in black, this 650 CFM street/strip carb is built around ATM’s all‑aluminum die cast main bodies, metering blocks and throttle bodies for strength, consistency, and a lightweight profile that doesn’t compromise tuning flexibility.
Key features
- All-aluminum construction: Die cast main bodies, metering blocks and throttle bodies deliver reliable, repeatable performance—at a cost lower than billet equivalents.
- Dual inlet, dual site-window fuel bowls: 7/8‑20 inverted flare inlets ensure secure fuel delivery and easy accessory plumbing for race setups.
- Extensive tuning capability: Changeable idle and high‑speed air bleeds along with adjustable idle feed and power‑valve channel restrictions give you endless fine‑tuning options for different atmospheric conditions and race combinations.
- Vacuum‑ready throttle bodies: Four vacuum tubes provide vacuum advance and convenient PVC hookups, supporting reliable ignition timing and compatibility with common vacuum systems.
- Race‑ready out of the box: Factory calibration is precise for immediate performance, with only minor trim required to match your specific track conditions and engine combo.
- Flange and compatibility: 4150‑style flange with 650 CFM capacity (also available in 750, 850, 950 and 1050 CFM variants for broader 4150 applications), giving you a scalable option for different builds.
- Finish and form: Sleek black finish with the trusted ATM XRSC design philosophy, combining street practicality with strip‑ready tunability.
- Ideal for street‑to‑strip race applications: robust, tunable performance without the premium price of billet components. This carburetor is designed to be a direct, reliable upgrade for engines configured around a 4150 style intake, delivering steady throttle response, strong idle quality, and broad calibration potential across a range of power adder setups.
