This carburetor is intended for Dodge and Plymouth trucks from approximately 1966 through 1973 that used the 273 or 318 cubic inch V8 engines. Confirm fitment with your vehicle's model year, engine size and intake manifold pattern before purchase.
C2-BBD is the cast/model code used by Chrysler for a specific 2-barrel carburetor family. 'C2' indicates a mid-1960s design series and 'BBD' identifies the particular model and configuration. Exact internal parts and calibration can vary by casting date.
This is a 2-barrel (dual venturi) carburetor designed to replace the factory 2-barrel units used on the listed 273 and 318 engines.
Product descriptions vary by seller. Some listings offer fully rebuilt or remanufactured units while others sell new-old-stock. Check the specific listing or contact the seller to confirm the condition and whether a machining or rebuilding certificate is included.
In many cases gaskets and hardware are not included and must be purchased separately. Some sellers add a rebuild kit or gasket set as part of a complete supply. Always verify the included parts in the product listing before ordering.
If your intake manifold uses the same flange pattern for the original C2-BBD-style 2-barrel carb (common on 273/318 applications), it should be a direct bolt-on. However, variations in aftermarket manifolds, spacer plates, or emissions equipment can require modifications or adapters.
Carb jetting may need adjustment based on engine condition, cam profile, altitude and ignition timing. The carb may come with standard jets; you might need richer or leaner main/idle jets during tuning. A professional tune or a carburetor specialist is recommended if you're not experienced.
Basic mechanical skills and common hand tools (wrenches, screwdrivers, pliers) are typically sufficient for bolt-on installation. For proper tuning you may need a vacuum gauge, tachometer, and knowledge of distributor timing and idle mixture adjustment. If you aren't comfortable, have a qualified mechanic install and tune it.
Choke configuration can vary. Many C2-BBD carbs used a heat-controlled automatic choke, but some late or aftermarket versions may be manual. Confirm choke type with the seller if automatic/manual operation matters to you.
Yes, mechanically there is no difference in running on unleaded gasoline. However, prolonged use of modern ethanol-blended fuels (E10, etc.) can accelerate deterioration of some rubber, cork and plastic components in older carbs. Consider replacing seals and gaskets with ethanol-resistant parts when rebuilding or installing.
Vehicles originally equipped with this carb type were certified under 1960s–1970s emissions standards. If your vehicle is subject to modern emissions inspections or regulations, check local laws—some jurisdictions require original equipment or specific emissions controls. This carb itself does not add modern emissions controls.
Regular maintenance includes keeping fuel filters clean, using fresh fuel, checking and replacing gaskets/seals as needed, cleaning the idle and main passages, and periodic adjustment of idle speed and mixture. If running on ethanol fuels, replace soft parts with ethanol-safe materials.
Warranty and return policies vary by seller. Many rebuilt/remanufactured carbs include a limited warranty (e.g., 30–90 days) against defects. Review the seller's listing for warranty length, return window and any requirements (such as core returns or proof of installation).
Common causes include incorrect float level, stuck float needle, wrong jets, vacuum leaks, or incorrect ignition timing. Start by checking for fuel leaks, proper float height, correct vacuum connections, and distributor timing. If problems persist, have the carb inspected by a professional rebuilder.
Yes — performance modifications can include rejetting, changing the accelerator pump, installing a different air cleaner or spacer, and modifying secondary circuitry where applicable. Be sure modifications are matched to your engine's cam, exhaust and intake to avoid drivability problems.
