The Hilborn RAW "Race-And-Win" Injector is the classic racing unit for the standard Gen 1 Small Block Chevy. These D-flared steel ram tubes for the SBC RAW EFI-R kits are available for both the 2-3/16-inch and 2-7/16-inch throttle sizes in 8-inch and 12-inch lengths. The ram tubes are intended for Hilborn SBC RAW mechanical and electronic stack fuel injection as well as other applications requiring a D-flare ram tube for 2-3/16-inch and 2-7/16-inch throttle bore injectors.

The Hilborn EFI-R injector manifold kits combine the technology of Electronic Fuel Injection with the racing born performance and aggressive looks of Individual-Runner engine induction.
