About this item
- VERIFY YOUR BOLT PATTERN (LARGE BASE ONLY): This is the "Large Base" Rochester 2GC model. The mounting bolt pattern measures 3 11/16" x 2 1/16". If your manifold measures 3 1/4" x 1 7/8", you need the "Small Base" version. Please measure your intake manifold before ordering to ensure a direct fit.
- AUTOMATIC HOT AIR CHOKE: Features an integral hot air choke system with a thermostatic coil housed in the round black casing. Connects directly to your heat stove tube from the exhaust manifold for reliable cold starts. Includes a vacuum port for the choke pull-off to prevent flooding.
- PLUG & PLAY PERFORMANCE: Pre-calibrated for 5.7L (350) and 6.6L (400) Small Block Chevy V8 engines. Idle mixture screws are pre-set but adjustable for fine-tuning to your specific elevation.
- RESTORE FACTORY POWER: Replaces aging, leaking OEM 2-Jet carburetors. Designed to solve common issues like hard starting, erratic idling, and flat spots during acceleration. Returns your classic truck or muscle car to smooth, reliable stock performance.
- COMPLETE INSTALLATION KIT: Includes 1x Large Base 2GC Carburetor, 1x Mounting Base Gasket, and new Fuel Filter (pre-installed). Note: Does not fit 4.3L V6 S10 models.
