I've been in the auto parts business for 56 years. My first boss told me something I've never forgotten. "A credit is MORE important than an invoice". If you sell a part to someone and they have a problem with IT! If you do and you do it properly, you'll have a customer for life. If you mess it up or make it hard for him, you'll never see him again. I can't believe you're going to give them another chance. They'd never get another dime of my money. Good luck.

I put a Sniper on my 408 68 Dart and it’s been outstanding. Start up is incredible and it hasn’t given me a problem so far in 3 years

I had the 4500 Sniper on my 582 ci bbc and had the same flooding issue that turned out to be a bad unit, Holley replaced quick and easy no hassle. It ran ok for a few 100 miles it then started idling at 2500 at a stop light in an 800+ motor with 0% throttle position and iac at 1%. I went back to carb as soon as I got it home because i was tired of every Sniper issue risking an expensive motor or transmission.

I am an avionics technician and have had extensive training in cables soldering and crimping. I heard your comment on wanting soldered connections and what I have been told in my training was crimp connections are stronger than soldering. I hear all the time in the automotive side that people think soldering is better than crimping and that isn’t always the case. There are times where soldering is preferred but crimped connections are stronger. What you do need to do is provide strain relief for all crimped connections. I use the uninsulated crimps and use heat shrink on top, this provides a clean look as clean as a soldered connection and the strain relief. I do agree don’t use the quick connections from the auto parts stores, I know Napa sells the uninsulated but joints.

Carbs for life here! Been working fine for hundreds of years. I’m in control with my cars and trucks. And they can be fixed in my shop or on the road.

I think if enough people spent time reading the Holly's EFI website and looking at the issues they would find it may not be what they're looking for. Holly's own website shows that their main issues are cold start drivability issues and fuel economy, all of the reasons most people switch to EFI.

Man...That Buick is beautiful !
Looks like my 1963 Riviera. Even the color is the same.I hope you keep it forever.

[wardfrahler]

Thank you for your honesty. I already bought a Fi-tech, haven’t installed it yet but I kept all the carb stuff as a backup.

[brigond]

I'm SO glad I kept my carbeureter! I was Very close to going for one of these units . I followed my gut feeling and waited.
Thank you. . This will help a lot of people.
I think all the customer service sucks on for all the companies that make them. Especially for returns .
I've decided to learn as much as possible about carbeureters and stick with what works reliability.

I was seriously considering a Holley Sniper for my '68 Cougar and after watching this, I'm reconsidering. I'm sticking with my Holley 4bbl on it. The Holley EFI systems have too many Chinesium parts in them. I agree with those Carter AFB's/ Edelbrock carburetors. Put a Edelbrock manifold, 4105 and matching Edelbrock fuel pump on my buddy's '75 El Camino. The thing runs like a top. Idle is glassy smooth. I'm sticking to carbs. I'm so glad I watched this video.

I did a sniper system on my 70 Impala. All went great and worked for about one year then two temp sensors went out. Of course the sniper doesn’t know what to do without temp input. Went thru Holley tech support. After several tries and long hold times I finally got a tech on the phone. No problem they over nighted me another system. I do think it was a refurbished system but I gave it a try. After 1 week the timing then stopped reading. I also had installed the Holley distributor that works with the system. After over a year of my car sitting there I finally said heck with it and put my HEI distributor and Eldelbrock carb back on. Now I’m back to driving to shows and cruises. Thanks for your video!

[dgambrel]

I have wanted to do a sniper for a long time. The more I look into it the more I think I’m good with a carb.

[hardball]

Your experiences are mine also. I've had to run through installs for friends that claimed these units were junk. Yes, I have had a few bad sensors but mostly the problems encountered were bad wiring, dirty power, plug wires were a big problem, basically installation problems. I have found both the Holly and Fitech units to be reliable but you just can't just throw the them in with Scotch Locks and electrical tape. I understand your position and problems and believe me I've been there too and if I had experienced your problems my solution would probably be the same. I'm currently running a Fitech Ultimate LS injection kit on a 5.3 swapped '68 C10 and love it but it's not for everyone.

I went through the same thing with a FItech FI. After two weeks and another display still never worked right. Took original Q-jet to a guy that only does Q-jets.He rebuilt and informed me I wasn't alone. I totally trust the carb.

[DragonFireEngneering]

If you are comfortable working on carbs, before converting to fuel injection, install a decent air fuel ratio meter. This is a game changer in that you can see exactly what the carb is doing. From there, tuning and/or trouble shooting becomes VERY easy, especially if you have a 4150 or 4160 Holley carb. I have done this on both of my carbureted cars now and they run so well that there is absolutely no reason to convert to EFI.

I have a 1971 ford bronco with a jasper 302 motor. I just went to fuel injection and I did my research. I almost went with the Holley sniper kit until I met the fitech guys at a car show. I went with the fitech, it had way less parts and a 1/4 of the price. I love it. I went to hot august nights in Reno and the fitech company had a tent there. They pulled me into the tent and cleaned up the parameters to be more efficient. It was the inventor of fitech that got his hands dirty. They now have a customer for life. Customer service is unbelievable and so is sales and tech support.

I have put two of these Sniper systems on our 1980 P-30 stepvans. They were properly installed by the book, every connection soldered, any extra wires depinned and removed. We have had the issue of rfi causing the hand held to freeze up and also raising the idle speed of the engine. I was on the phone with Holly and the tech guy that was helping me ended up saying the unit was defective and sent us another one, and only the main unit. We installed the new one and programmed it and it did the same thing. Funny thing is is that it would behave fine at first and then after driving around for 30 min or so you would notice the idle creeping up and then the hand held would start freezing. If you shut off the engine and restarted it it would be fine again for about 30 min and then the symptoms would happen again. I got on the phone with Holley again and this time I got a tech guy that was aware of the rfi issues and told me to foil all the spark plug wires and ground the foil so I did. I also foiled the hei distributor as well and grounded that foil as well. That fixed the problem with the rfi. The next problem we had was the secondaries sticking open a tiny bit causing the idle to be high and until we figured out what was happening we were trying to compensate by lowering the minimum idle air and of coarse this means you have to reset your tps as well. Well the funny part is that when you would shut off the engine and the vacuum would bleed away the secondaries would fully shut. We then figured out that the friction in the throttle shaft was too high when you had vacuum on one side of the throttle plates. We tried to fix this by wrapping the secondary throttle shaft return spring one more wrap which did work somewhat... I can tell you that I have spent a lot of time messing with these because of these problems that Holly failed to address before they released the sniper units. If I had put this system on a T-Bucket with an exposed engine that you would be showing off then I would have been really upset since the engine in the stepvan looks pretty stupid with all the foil on the wires and distributor. Hopefully the Sniper2 will be better...It sucks when you tell your boss that we can put fuel injection on work trucks "these p-30 stepvans were A/C install trucks that were driven every day." and then have to explain to him why we are having all these drivability problems. I feel bad for the weekend mechanic that buys this system for his hot rod thinking they are going to have a great trouble free experience with a properly installed Holly fuel injection system...Once again lets hope the Sniper2 is better...
I hope me sharing my experience will help somebody that is going through what I went through with these units.

So I had a carb that ran great, went to fitech and I couldn’t get it to run right all the time. Went back to carb but… I took the ECU from the fitech and hooked up all the inputs including the TPS. Now I can data log the carb and make adjustments as needed. If the ECU dies, I’m still cruising.

[Higgsgarage]

Great explanation and good info for people wanting to do this. Thanks for putting out a transparent video on the Sniper.
