Holley Sniper EFI, MSD on 5.3 LS truck engine!!! Third Gen Camaro LS swap!!!

[@SmashNGrabRegul8t0r]

....and with all that being said and done, you're putting it in a SUPER COOL car that we all love and grew up on loving in the late 80's early 90's

[@andre1dre]

This video is exactly what I was looking for. You've answered so many questions I had. This is everything I'm trying to do to my '88 T/A, thanks.

[@carltonfortune6846]

How far u get?

[@fuzzy19111]

I'm in the process of an lq4 ss2 cammed sniper swap in my ventura. This info is great.

[@dieselapegarage]

Appreciate the tips and tricks 👀🍿 watching an learning keep it coming

[@dandorris8531]

Subbed, thinking of doing the same on my 6.0 4l80e 70 chevelle just to keep the old school look.

[@gobabygo48]

im doing the same combo on my K10. aluminum block LS2... did you end up going this route? cant decide if i wqnt to go this route or with the fuel rail/intake/injector set up.

[@MAJorgy70]

Looking forward to watching this come together 👍

[@Colton.ontheadventure]

Will be following. I was considering doing this for a simpler fuel injected motor

Great video. I just ordered the same holley injection system. For a 5.3 I put in an 84 K5 blazer. I have the holley duel plane intake. And I've had 5 different carbs on it. Tuned ever which way from Sunday. And never got the off idle stumble to go away. I've taken a carb right off my third gen. 350 camaro. That runs perfectly. And it would stumble. They all ran perfectly down the road. But had a dead spot off idle. So I thought I'd try the holley injection. Glad you mentioned the MSD compatibility. I have the MSD 6014. Works great and easy install. I just wonder if I will have to install another temp sensor or if I can tie into the one that the MSD box uses. And I already have a Bosch O2 sensor and AFR gauge. So ill probably have to put another one on to send signal to the injection system. I also have a 3/8" return line already on the blazer, I hope it will work for this system. My engine is an all stock long block from rock auto. Good luck with your swap.

[@limabravo6065]

These aftermarket self contained efi throttle bodies are a modern form of the old chevy TBI deals. They took a 4150 style throttle body and added injectors to the sides where some even look like holley style fuel bowls. And instead of hosing down into the intake these things use annular rings with a bunch of little holes in them which gives good atomization and gets the injectors out of the air stream. And the injectors are based on the LS3 units as far as how long and wide they are and like dude said they run stupid amounts of fuel per hour and if you want to you can get the injectors from the bigger aka more expensive sniper system and install them into your deal (cfm on the throttle bodies are the same until you get into the terminator series) and after a little reprogramming your TB can support 800 instead of 650h👍. And self tune will work as advertised for everything but full throttle you need a wide band and log your data

[@rickshafer6199]

You’re making me want to do this cause its seeming really easy now. Looking forward to more videos on this car. P.s. your making me sea sick with all the movements though. Slow down or get a tripod

[@dylanholbert7964]

Beginning to start an ls swap for my 3rd gen this video helped a ton. I Appreciate it man

[@Wilson_Racing]

I put a 525LPH hellcat pump in my 3rd gen to fuel my Sniper Stealth 4150. I'll never have to drop my tank ever again

[@theshark2804]

This setup looks like it saves money. The only option is to run an msd pro-flo or fitech ls retro. I would like to run Holley and this setup like nice

[@kenyadumas4631]

Man I loved this video I have a 89 convertible camaro that I’ve had for about a couple months I recently purchased an 5.3 ls so I’m definitely going to stealing a few ideas here in there....can you pm a ruff estimate of how much you spend I have a wife too lol

I have an ls that is carbed in my car this seems to be the best way for me to change it to efi

[@akp41]

Thank you

[@C8corvetteobsession901]

Depending on the model LS, you may NOT need an adapter for the trans. I believe 2004 and up models don’t need it. I struggled with mine trying to install trans and that flywheel already have the adapter built into it.

[@alangomas8702]

I’m thinking of doing this to my 86k20. How is she doing 3 years later bubba.

[@gdtengine3935]

Good info... I've been debating building a 383 from my bone stock tbi 350 in a 1988 short fleet pickup or swapping the little 5.3 I have from a 2004 Tahoe with roughly 140k but just didn't want the harness hassle. I have a 1977 CJ5 that I installed the MSD Atomic EFI on and that old engine will now pass emissions and runs great...so I've wondered if this had been done yet and looks like you've got a really clean and efficient build and have truly helped me make a final decision. Thanks for the information. I have one question and that is what you were referring to on the timing cover that I'm not aware of and didn't see updated on any of your other posts....? What am I missing there? Thank you again. Clean build. Congrats. GT

[@TravisBramble]

We’re did u connect the yellow coil input and the green and purple wires ?

[@michaelcuoco3204]

Hi Bro is your car up and running,I was thinking about getting the same efi kit ,,, i have Fast EZEFI 1.0 and ran likena top for. One year and now the ecu is wak ,,,,i have a 427 Texas speed Stroker Naturally aspirated 650 Hoss ,I hope and pray your install went smooth ,,,please let me know ,if it went the way. It was supposed to I'll go ahead and swap my Ezefi kit for the SNiper ,thank you

[@esp68camaross33]

What about the wires to use? Seems like there's maybe 6 wires to use for an ls with the sniper.

[@drakedavis4512]

So I installed the sniper and ls1 msd box hooked the yellow wire from the sniper to the grey wire on msd box the truck will prime but the setup wizard will not work keeps giving me a error code

[@KravasGarage]

Pretty sure it was purple and grey when i did it.. might have changed over time..

[@thabigghomie_]

Hi good stuff Would that work On a 4.8liter 2008 chevy That Holley Sniper And would that work with the DBW for the fas pedal

Can’t wait to see more but please stop all the moving around so much making us dizzy and sea sick but love the content

[@cameronmccormick4902]

When it came to the ignition what wires did you connect between the 6014 box and the Holley sniper?

[@jeromebradley6860]

Can you use stock hood.

[@Albert-do4xp]

What do you set the msd box as far as timing goes, and do you connect the white wire from Holley to the grey wire on msd?

[@Moparbarnett88]

Great video, where did you get the oil pan I am lookin for one as well for great price. Did you have to modify the windage tray

[@mavcar38]

Do you still have this car and setup? Can you give a review on the sniper? Thanks

[@KravasGarage]

Working on the car right now, Sniper had been flawless, will soon find out how it handles boost!

[@jorgelara6528]

Where did you get the oil pan set ? Thanks and great videos btw!

[@gustavoreynoso6849]

I was wondering what did you do with the original wiring harness

[@joeingalls9553]

Did you have to do a DOD/AFM delete on the engine? Do you have a part # for the oil pan kit?

[@quinnrobbs8476]

I’m doing a 5.3 swap on my 84 3rd gen. Do you have part numbers for the stuff you ordered? The pan and the mounts?

[@thabigghomie_]

Do u have links for your parts did tht intake & holley efi & msd come in 1 kit

[@detlion79]

What wire did you use for tach signal from your msd box to go to the sniper?

[@KravasGarage]

I believe it was the grey wire, went to purple on the sniper (set to CD box). i also doubled this wire going to my monster tach but I'm going to change this to the tach signal output from the sniper to reduce the risk of interference..

[@332ARA]

I'm doing something similar with with a FiTech. So do you end up just connecting all 3 Tach wires together? (FI, Ignition, and Tachometer)

[@262ctb]

Is that a sniper 2 model?

[@bryanbell9183]

How did you hook up to the coils on this setup? I am running this setup on my 76 camaro thank you

[@KravasGarage]

The MSD plugs directly into the coil harness' on each bank.

[@bradhall6954]

How easy/hard is it to start. I’m considering going this way. I currently have msd box on my ls and it’s carb’d but it is always hard to start. I’ve adjusted the carb every which way and still no luck.

[@KravasGarage]

Sniper fires up just as good as my '18 F150.. have you adjusted your start up timing on the MSD?

[@gdtengine3935]

I put the Holley super sniper stealth on and have a start stall issue. Been over wiring time and again fuel pressure is 58 lbs. have you had any issues like that? Just trying to get some ideas. I've spoke with Holley and they're sending me a new CTS because my CTS reading on my handheld is reading Error/Low. But I'm not convinced that's the issue but it's a starting point. Any help would be appreciated

[@KravasGarage]

My first start attempt I had my RPM signal wire to the Sniper come disconnected.. the sniper would prime fuel with key on enough to make it start for a second or two then die.. the fuel pump and injectors will not continue to run without an RPM signal.

[@henryrangel7354]

What was included with the refurbished sniper?

[@ryanmatthews3798]

Where did you get the plugs for injector holes ? I’m going same exact route however I have to plug my injector holes

[@KravasGarage]

My intake doesn't have injector ports..sounds like yours might be set up for a throttle body with fuel rails?

[@tjpruitt1374]

How did the swap end up did your fuel system turn out good with the sniper system and also MSD this is the route I’m planning on going with my 72 nova

[@KravasGarage]

Ran it all season at the track with zero issues!

[@blakesracingandoff-road6353]

I got the exact same setup in my mudtruck Holley EFI single plane 5.3 with msd. I need to get mine tuned in it's running rich as hell from the factory. Did you get somebody to tune yours or do it yourself?

[@KravasGarage]

I have done zero tuning to the sniper, when I first started the car it had open headers with the O2 about 6" from the end of the header and ran extremely rich untill I completed the exhaust.

[@turbochevelle5641]

Unlike popular belief they do have to be tuned. The self learning will only get you so far.

[@Messiahdagod]

Did you have to cut crossmember to make it work

[@KravasGarage]

Negative. But I'm not running a/c either.

[@Messiahdagod]

@@KravasGarage so if I want to run the stock ac compressor I’ll have to cut that piece out

[@KravasGarage]

In the stock location, yes. Not to say you couldn't relocate the compressor up higher with a different accessory set up. Or it may be possible with a tubular K-member. (I will be installed one in the next video!)

[@Messiahdagod]

@@KravasGarage yeah I found a bracket for the old school pancake compressor

[@limabravo6065]

How many big brains have given you all the many reasons that using the tbi setup is wrong?

[@victorhinojosa8006]

So you don't need the original wiring harness off the LS? I have a sniper on my 350 sbc and was thinking of upgrading to an ls.

[@KravasGarage]

No, the sniper will cross over fine, but you will need an ignition controller to read the cam and crank sensors and run the coil packs, etc.. pretty cheap to do..

[@Crodgers88]

@@KravasGarage do you have a link for this?

[@markmcintosh6968]

Would you do anything different?

[@MHolt3573]

I'm doing the same setup in a 72 c10. Do I need to hook the tach wire from the box to the sniper somehow.

[@KravasGarage]

Yes, the sniper needs to see an RPM signal. Use the tach output wire from the MSD and hook it to the tach input on the sniper.

[@MHolt3573]

@@KravasGarage we tried to crank it last week but it was spitting and popping like it was out of time.

[@MrPrelude98]

Where did ypu buy ypur oil pan?

[@billysandoval6316]

Does the msd box and sniper system both need to connect to cam or crank sensor?

[@KravasGarage]

MSD connects to cam and crank, Sniper uses an RPM input from the MSD.

[@Moparbarnett88]

What radiator and fan is that

[@Mrwhatarethose]

What kinda power does it make?

[@amberbrown1693]

Hey I got both systems does the msd grey wire go to were on my sniper or how does that work

[@KravasGarage]

Purple I believe, the MSD needs to send an RPM signal to the sniper so it know when to fire the injectors.

[@amberbrown1693]

Ok so not the purple and violet ignition from the sniper

[@jamesamoscones977]

hi do i need the msd box to run the sniper ? an do the harness come with it

[@nsmturbo5902]

You will need something to control your timing if you're using a "carburetor" style manifold. MSD 6014 is the cheapest way to go in an application like this. If you're using an electronic (4l60e/4l80e) transmission you will need to have a way of controlling that too. The Holley Terminator X Max will control everything

[@shandyz71]

part number in this intake ?? and what heads do you have.

[@shandyz71]

cathedral or rectangle heads too?

[@KravasGarage]

300-132BK I believe.. if I could do it again I would get the dual plane intake for the better mid range torque.. I've got cathedral port 862s.

[@shandyz71]

sweet thanks man, I just received my sniper 2.0. how does it work with the msd6014?? I’ve heard it doesn’t work but I don’t think that’s true

[@KravasGarage]

@@shandyz71 all the sniper needs is an RPM signal.. MSD should have a tach output that works for the sniper.

[@shandyz71]

⁠@@KravasGarageyeah my 6014 just came in and it looks like it will work. do you have Facebook or something? I may need your opinion later on once I put her in

[@carltonfortune6846]

How did you connect the msd to sniper??

[@KravasGarage]

The Sniper gets an RPM output signal from the MSD..that's the only communication between the two units.

[@slaskey]

Can you carburete that ls engine

[@KravasGarage]

Yes. Same concept as the Sniper I used.

[@Vin-qz5om]

Did you use stock oem temp sensor ??

[@KravasGarage]

Yes, actually running a two separate sensors, one in each head, one for the sniper, the other for the MSD box.

[@Vin-qz5om]

@@KravasGarage Awesome, I ohm tested temp sensor that came with efi vs stock ls sensor and they're the same. Thanks

[@EatPezzzz]

Except no 5.3 was ever an LS motor. They were LM, L3 or whatever. Yes, the LM is in the same family as the LS, but that doesn't make them the same.

[@scice2827]

The LS4 that came in the FWD cars like the Impala SS were 5.3 liter engines

[@chancecolwell3823]

Dose it have a OBD2 port

[@KravasGarage]

No, the touch screen allows for most of the user adjustable options as well as data logging. It also has an SD card that can be pulled and used for more in depth tuning.
