Today's fuels are blended for modern fuel injection, not that old 2 Jet carburetor from 50+ years ago.\n\nHolley makes it easy to convert your classic car with a Rochester 2GC Large Bore two barrel carburetor to fuel injection. The Sniper EFI 2GC Large Bore is a bolt on electronic fuel injection system that will put the fun back in your classic ride.\n\nThe Rochester 2GC Large Bore carburetor was commonly used on 1974 - 1978 Chevrolet, GMC, Oldsmobile, and Pontiac vehicles such as the Camaro, Firebird, El Camino, Corvette, Omega and most C-10 through K3500 series trucks. Check out our year\/make\/model application search at Holley.com!\n\nInstallation of the Sniper EFI 2GC Large Bore throttle body is simple and straightforward:\n\n¥\tRemove your current carburetor and bolt on the new Sniper EFI system. No intake manifold adapters required!\n\n¥\tReinstall your factory or custom air cleaner. The Sniper EFI 2GC air cleaner flange matches the Rochester 2GC so it accepts most factory air cleaners.\n\nNot only does the Sniper EFI 2GC offer superior throttle response and WOT power over the carburetor, but you may also benefit from increased fuel economy! Put an end to cold start issues, hesitations, vapor lock, and flooding with the accuracy of EFI. You can also use the Sniper EFI 2GC to control the ignition timing, taking EFI to the next level. The Sniper EFI 2GC system is capable of supporting 350 HP on naturally aspirated engines.
