With the 4500/Dominator flange, there's only one choice and it will cover all your bases. If you're replacing a Dominator carburetor with the Sniper EFI Stealth 4500 system, you're making some serious power and Sniper EFI can back it up. The Stealth gives you the same classic looks as a Dominator carburetor with modern technology hidden inside. While the standard Sniper EFI system is filled with four 100 lb/hr injectors, the Stealth 4500 packs eight of those injectors to support up to 1500 horsepower. It also houses a 2.5 bar MAP sensor to accommodate up to 21.5 psi of boost. The only decision you need to make is which color you want it in.
