Product Details

The Sniper EFI 550-866 is a bolt-on throttle body fuel injection system engineered to replace Rochester 2GC small bore two-barrel carburetors on 1955-1969 GM vehicles. Finished in Classic Gold, this self-tuning EFI system delivers modern fuel efficiency and performance while maintaining the classic underhood appearance.

Key Features:

  • Self-tuning ECU with integrated throttle body-mounted design eliminates the need for separate control boxes
  • High-resolution full-color touchscreen for initial setup, tuning adjustments, and real-time gauge displays
  • Genuine Bosch LSU 4.9 wideband oxygen sensor provides continuous fuel map learning for optimal performance
  • Designed to fit most factory 2GC air cleaner assemblies for a clean, stock appearance
  • Universal throttle lever includes provisions for TH350, 700R4, and 200-4R transmission kickdown
  • OEM-style throttle position sensor, idle air control, and fuel pressure regulator ensure years of reliable service
  • Direct bolt-on installation to factory Rochester 2GC small bore intake manifolds with no adapter required

This system is not designed for Tri-Power installations. The Sniper EFI 550-866 provides a complete plug-and-play solution for classic GM vehicles, combining cutting-edge fuel injection technology with period-correct aesthetics in a stunning Classic Gold finish.
