Fits IH V8 Factory Spreadbore Intakes with Grinding to Thermostat Housing
Holley Sniper EFI Quadrajet self-tuning fuel injection systems are ideal replacements when you're tired of rebuilding the 50-plus-year-old Rochester Quadrajet (Q-jet) on your classic ride. They're the first bolt-on, spread-bore, EFI throttle-body systems not requiring any additional adapters, sealing plates, or intake manifold swaps. They retain the same great features as the 4150 Sniper EFI version (four 100 lbs.-hr. injectors; built-in timing control; high resolution 3.5 in. full color touchscreen; etc.). Their throttle body will support naturally aspirated power up to 500 hp. In addition, they offer multiple fuel inlet configurations that allow for a stock-appearing installation and fit most stock air cleaners. Modernize your Q-jet-powered classic vehicle with a Holley Sniper EFI Quadrajet self-tuning fuel injection system.
