EFI Replacement for the Rochester 2GC Carburetor
The first thing to ask yourself before buying the Sniper 2GC EFI System to replace the Rochester 2GC carburetor on your car or truck is, "Do my requirements mandate the use of a 2GC direct-replacement. This could be the case if you have a very tight hood clearance issue (no room for an adapter plate), if you are unwilling to replace your 2GC air filter setup and if you are interested in the easiest possible, direct-fit installation. If this is the case then this EFI system was designed with you in mind.
However, if the paragraph doesn't precisely describe you then you may want to consider the Sniper 2300 EFI System. Holley 2300 system flows far more air, costs significantly less, and can usually be adapted to any 2GC intake manifold with an inexpensive adapter. Check it out.
Check out these features of the Sniper 2GC EFI System:
- Bolts directly to factory 2GC manifold
- Connects directly to factory linkage
- Mates directly to factory air cleaner assembly
- Self-configuring, self-learning
- Includes built-in fuel pressure regulator
- Visually amazing 3.5-inch touchscreen provides both setup and monitoring
- Available in Shiny Metallic, Ceramic Black, or Classic Gold
- Available as 2GC Small or Large Bore Versions
Sniper 2GC Small Bore EFI System: 550-864 (Silver), 550-865 (Black), 550-866 (Gold)
Sniper 2GC Large Bore EFI System: 550-855 (Silver), 550-857 (Gold)
The Sniper 2GC makes this easy. Toss that old 2GC carburetor because this bolts directly in place of the original 2GC carburetor on the factory manifold and connects to the factory linkage. Yes, you will install an O2 sensor and Holley makes that easy with a clamp-on O2 sensor bung--no welding required. Screw in a coolant temperature sensor, wire up power, ground, and your ignition and you've done with the EFI system installation.
Think the installation was easy? Then you will really love the configuration! A gorgeous 3.5-inch touchscreen display is included in the kit and lights up when you first key on the system. Select "Wizards" and be prepared to answer some questions so easy you'll feel like a genius. Questions like "How Many Cylinders" and "Engine Displacement". (Hint: If you need some help on that last one it's probably 258.) The Wizard completes the configuration and pre-programs a perfect start-up tune. By starting the engine and driving the tune just gets better with time--without you doing anything other than enjoying yourself.
Recommended With Your Sniper 2GC EFI System:
- You will need an EFI Fuel System. We have several solutions!
- We always recommend one of Holley's OE Style Fuel Modules if one is available for your vehicle.
- A complete EFI Fuel Tank System is also a great choice.
- If no OE module or complete Tank solution is available for your vehicle but you still want the benefits of an in-tank pump then one of these Retro-Fit Fuel Tank Modules is the right answer.
- The Master Kit with inline fuel pump continues to be the most cost-effective and universal solution. You can choose that when you add the EFI System to your cart, above.
- You absolutely will want a Fuel Pressure Gauge. Those who don't install one with their EFI system are invariably the ones who end up needing it. Don't be that guy!
- The Sniper EFI System has the capability to control ignition timing in addition to providing fuel injection. If you choose this then we recommend you upgrade to the HyperSpark Distributor System.
