Description
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. They are offered individually or in Master kits with external fuel pressure regulator preset to 58.5 psi, 20 ft. of 3/8 in. Vapor Guard fuel hose, fuel pump, filters, necessary hardware, and bulkhead fitting to return fuel into the tank.
Features, items, and specs:
* Designed to deliver the signature "Rochester Roar" at wide-open throttle!
* Throttle body-mounted ECU–no extra boxes to mount
* Only 4 wiring connections required (battery positive and negative, switched ignition, and rpm)
* Transmission provisions on throttle lever for TH350/TH400 and 200R4/700R4
* Universal throttle and transmission kick-down bracket

* Internal fuel pressure regulator preset to 58.5 psi
* 20 ft. of 3/8 in. Vapor Guard fuel hose
* Fuel pump and filters
* Necessary hardware and bulkhead fitting to return fuel to the tank
