Got a Holley Sniper Stealth EFI & I love it.

I’m in, I need to price out the complete install on my 401 Javelin Amx. But that’s definitely the look I want. 🤘🏻

While this looks great, would be really cool if you guys would do throttle bodies that look like the 4160 carbs with side pivot looking fuel bowl ends and are short enough to be run end to end on a 2x4 manifold, like the 427 medium riser FE Ford with dual quads. Lots of Ford and Cobra guys would really go for that.

When running a stand alone coil u need the coil driver? Or can you with out? And is this the same in the sniper?

[stevedriver]

i see a lot of youtube stuff where a good motor runs beautifull with the EFI but the good old carby made a little more hp in runs.i just bought the sniper stealth to replace my 750street hp that was great when driving but hard to start first time and eventually fouled the plugs over 20 or so starts. AND believe me a drive down the freeway a few times will not clean black/ sooty spark plugs. Steve in Australia

Are there any advantages over the original sniper other than looks?

[jefferywalton]

I just like the 4150 because I know my pricey Trick Flow throttle bracket will work. And my hood clearance shouldnt change from my existing 850 brawler.

Looks interesting, I have a 85’ C20 that we use for heavy towing, it’s mild 383 will soon be replaced by a 400 AFR headed SBC. The curb weight is 4900 lbs, is this EFI system best for this or do you recommend something different?

I have both, MSD Atomic efi and Holley Sniper.
I prefer MSD Atomic efi. 👍

Holley, have you fixed this junk yet? The ECU is easily affected by RFI and more money is required to shield the leads.

[AngryDuckSoup]

whats wrong with your head swinging randomly back and forth?

[deangelo]

I have a coil. So I must buy a coil driver?

[cybair]

The Sniper EFI should be engineered to use the standard fuel lines, fuel pump and float level fuel system while using only a pulse fuel injector controlled electronically. That would reduce the installation hassle to the oxygen sensor, the throttle body EFI and the display/computer. That would encourage more people to do the conversion.

Wish I could get you guys as a sponsor for my channel lol. Love your products so much better then edelbrock. Keep on making phenomenal products

[dallaswiens]
