Sniper EFI Selection Guide
When selecting the correct Sniper EFI system for your engine, there are only three questions we must answer:
- Which carburetor mounting flange does your intake manifold have?
- Are you using a supercharger or turbocharger?
- How much horsepower will your engine make?
Carburetor Mounting Flange
First, we'll verify which flange you'll need. For some applications, this will be the only question you'll need to answer. There are Sniper EFI systems compatible with the following eight flange types:
- Holley Squarebore 4150/4160
- Holley 2300
- Holley Spreadbore/Quadrajet™
- Holley 4500/Dominator
- Rochester Small Bore 2GC
- Rochester Large Bore 2GC
- Jeep BBD
- Autolite 1100
Below, you'll find full-size, printable diagrams that you can verify your flange with. Once you have determined which flange you have, click the corresponding link for the next step of the Sniper EFI selector.
Holley 4150/4160 Squarebore
It's no surprise that the most widely used intake flange has the widest range of options. From stock to up to 1375 horsepower, Sniper EFI can bring the reliability of EFI to your hot rod.
Holley 2300
From mild-to-wild, our Sniper EFI 2300 offerings can handle as much horsepower as you can cram through a 2-barrel intake manifold. If you're ready for a 21st century 2300 replacement, you're in the right spot.
Holley Spreadbore/Quadrajet™
Whether you want to replicate that Quadrajet™ roar with modern technology or take advantage of the dual-pattern base of our 4150-based Sniper systems for big power, what you need is at this link!
Holley 4500/Dominator
The Dominator flange is the epitome of "Go big, or go home," so we went big with a Stealth Sniper system that will let people know you mean business when they see your engine bay while backing that bark up with plenty of bite.
