Answering your questions about Holley's Sniper Stealth EFI

Ever since I installed Holley's Sniper stealth EFI on my 68 Camaro I have had tons of questions about it. I made this video to answer your most asked questions about the EFI system. If you have any other questions be sure to leave them in the comments below.

Do every thing this young man has said describes my experience with the sniper. My 63 year old truck (bit modified) has become my daily driver because it starts and drives like a modern reliable car. Really enjoying the vehicle now, not just a shed trophy.

I really appreciate your video bro! I am about to put sniper efi on my Chevelle and you sold me on it.

The amount of time I have in tuning my carb is probably more than what it took to install this 😅 I'm definitely going to look into it in the future

We've got our truck at The Shop getting new engine and tranny installed, sitting atop the new engine is the Sniper 550-510 unit. We upgraded for obviously more power, reliability and going it'll help fuel economy. The old big block was getting 7mpg out of a factory 2 barrel carb, this new engine is small block 351W bored .60 over and has been built up quite a bit but we're still around 500-550hp, even so it should get better fuel economy than the big block did😆

Thank you for this video, I’m considering installation of the EFI on my 351w I’m based in the UK and theres really not enough information that explains the pros & cons on this set up, so hearing it in a “Nutshell” was good enough for me! Thanks Again. 🇬🇧

First video of yours I’ve seen, immediately impressed with the quality and video style. Keep up the great work!

[michaelparadisis]

Great advice bro. You convinced me. I’m installing a Sniper 4500 on my BB Chevy as we speak.

[hotrodd]

Great video man! You have me convinced and gained a subscriber!

[cfmechanic]

I like my base sniper. Has issues here and there but overall am very satisfied going on 6 years with it

[travismopargarage]

good video man igot the Sniper X-flow its good for 800HP i have a built moper 408 in my truckand the x-flow works great on my truckafter a little tuning on it
and you talked about price now i had a fully built race carb on my truck that i paid $1300 for and the x-flow and the in fuel cell pump set up was around $2000 so the price differance really isn't that much and like you said the drivabilitly is so much better then the carb set up now i haven't had my truck on the track with the efi yet but it really doesn't feel like it has lost any power with the sniper ill just have to see if the truck still runs 6.70's in the 1/8 with EFI

If you already have the kit for 650 na and want to go boost, you can change the injectors to bigger ones and change the map to a gm 2 bar or 2.5 bar. You will have to change those perameters in tune tho. But it wasnt difficult at all.

great intro vid for holly sniper system i just got my car running with the super sniper set up i bought the whole 9 yards from holly they hooked me hook line and sinker and now i feel like im part owner of ther co. lol... anyways i got it running with there basic tune to make it happy to run but still needs alot of tuning im almost over whelmed with how many fine settings there is and almost dont know where to start im running twin turbos also i bought the holly pro dash it needs to be configured in it will probably take me of firguring out all this stuff . wish there was a vid for super sniper for dummys never the less i enjoyed your vid good job thanks Bill

[SS_Gang]

I'm definitely going carb efi however I believe most people don't have the proper carb setup. I have zero issues with my carb. The Only reason I'm going to switch to a efi carb is due to better fuel mileage

[MUSCLECREWDave]

Love my Sniper stealth, looks a lot better than the boxy regular snipers lol.
Question: a shop installed mine awhile back, they left harness with a thick connector wrapped up behind the unit on my intake manifold.(looks like a nest) What’s that for? can I delete that like you where saying at the start of this video?

[crouchingwombathiddenquoll]

Excellent informative video, thank you, from Australia ✌🏼🇦🇺🌏

[TheSonicusa]

Hey does that sump pump need’s return line

[timleonard]

Would you use this for initial start up and cam break in or would you trust carbs for that then swap over once the cams broken in

[rogercox]

I’ve heard some people say it cleans up the raw fuel smell. Obviously depends how carb is tuned, but have you noticed a reduction in gas smell while drive or sitting in the garage?

[donsvt]

I installed one on a 64 bel air and I ain’t getting any fuel to the injectors and also I have no pulse

[Nathan-slnv]

Do I have to buy another intake manifold to install sniper? I have a Pontiac performer from edlebrock.
