Same fit, no leakage, great value for the money. I saved over $250 in parts by installing instead of rebuilding the old beat up carburetor which was giving me grief. You just have to tweak it once installed but Youtube helped with that. The plus of this carburetor is apparently the parts can handle ethanol. Highly recommended so far. Review: Great. - Worked great on my 87 Chevy v8 350 small block. Bolted it on and adjusted the idle and never had a problem. Been working on my truck perfectly for 2 years ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B073V866PX | | Best Sellers Rank | #111,349 in Automotive ( See Top 100 in Automotive ) #433 in Automotive Replacement Carburetors | | Brand | Auto Parts Prodigy | | Brand Name | Auto Parts Prodigy | | Compatible with Vehicle Type | Car, Truck, Van | | Customer Reviews | 4.1 out of 5 stars 569 Reviews | | Exterior Finish | Metal | | Flange Type | Bolt On | | Fuel Type | Gasoline | | Manufacturer | Auto Parts Prodigy | | Manufacturer Part Number | ROCHESTER 2GC | | Model Number | ROCHESTER 2GC | | Part Interchange Info | replacement | | Recommended Uses For Product | Chevy Chevrolet Rochester This Rochester 2GC 2-Barrel Carburetor is compatible with various Chevrolet models equipped with 5.7L 350 (1970-1980) and 6.6L 400 (1970-1975) engines.
