Let's face it, you love driving your classic car, but dread the hassles with your Rochester 2GC carburetor. Today's fuels are blended for modern fuel injection, not that old 2Jet carburetor from 50+ years ago.

Holley makes it easy to convert your classic car with a small bolt pattern, two-barrel, Rochester 2GC carb to fuel injection. The Sniper EFI 2GC Small Bore is a bolt on electronic fuel injection system that will put the fun back in your classic ride.
The Rochester 2GC small bore carburetor was commonly used on 1955 - 1969 Chevrolet and Buick, Oldsmobile, and Pontiac vehicles such as the Camaro, Electra, Super 88, Tempest and most C-10 through K3500 series trucks.

Installation of the Sniper EFI 2GC Small Bore throttle body is simple and straightforward:
Remove your current carburetor and bolt on the new Sniper EFI system. No intake manifold adapters required!
Reinstall your factory or custom air cleaner. The Sniper EFI 2GC air cleaner flange matches the Rochester 2GC so it accepts most factory air cleaners.

Not 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.
