Carb vs Holley sniper Vs FiTech

Just getting ideas for my vortec swap. I also have a 4l60E that I may swap later on.
I’m considering going EFI instead or a carb since I need to run an electric fuel pump anyway
Is anyone running FiTech EFI ? They also make a compatible stand alone controller for a 4l60E

Or The Holley sniper ?? I’m not sure if they have a compatible trans controller.
I think I’d prefer to have them integrated together if I do swap the trans

I swapped out my carb for a Holley Sniper on my 350 stroker and I have to say I love it. It starts like a charm now.

I went with FAST XFI Street EFI. I looked at several and they will all work better than a carb when you get it dialed in. The key thing to remember is that it will take some time and many hours of datalogging to sort out the fuel curve. This includes at many different outside air temperatures, warm up, acceleration, "pump shot" curve, and a few others. It is well worth the time though, and kinda cool to be able to change fuel delivery with a laptop. Do not get one of those self tuning kits, it takes too long for it to learn for each change you make, and it can't datalog. If you have tuned carbs, that will come in handy because the goal is still the same. The wideband O2 sensor is handy to use, even though mine runs better a bit richer across the board idle, cruise, WOT than pure stoich theory. Aftermarket EFI is one of the best things that's happened to the hot rod world Be sure to do a good install, then have fun tuning it.

What did you do for a fuel pump setup ? I’ve been looking at the Fitech-Tanks inc in tank setup.

I switched from a Quick Fuel 850 to Holley Sniper. Love it. Still haven't had it tuned yet. I do want to but don't see what that will get me. I starts right up and has great throttle response. Any one know how tuning will help?

Very nice!!!!

At first I was totally against the Q jet and got a lot of hate from the Q jet folks. The 800 CFM Q jet I bought from Chicago Carburetor for 600 bucks needed some tweaking but, finally got it dialed in, making brackets, fixing secondary issues and tuning. I was very close to junking this Q jet and going to a Holley 800 CFM carb or the Sniper set up but, I got the bugs out of the Q jet. On the dyno the Q jet's HP was almost the same as the Holley. The throttle response on the Q jet is on point 100% and fitment with 70 shaker set up was painless. I'm not running a choke because where I live it hardly ever gets cold and starts good without it. I would buy a roller cam and a nice set of roller rockers with money I would save buy running a Holley carb or a Q jet. The Sniper is really sensitive to interference and voltage drop and I have seen others deal with these issues. I know they work and work good but, the gain you get doesn't pencil out IMO.

The Sniper set up that I was going to use was the Quarda Jet look alike, everyone said would fit with minamal mods to the shaker but, Holly Cow! 2,700 bucks. I didn't know they cost that much. If HP is what your looking for I would spend it on other stuff but, if money is not a factor they work and you can really tune these things like crazy.

For me I want to make a reliable cruiser sort of old school pontiac meets new school technology. Lets face it 1976 400 4bbl has to be the worst 400, they detuned the heck out of it. So I am going to store the original stock motor and trans and build another 400 with turbo 400 trans. But back to the EFI, I have only put about 100 miles on it. The thing is still in learning mode, plus new cam and lifters. I haven't tried tune or anything.

put my Sniper on 3 years ago. Still learns. I want to have it tuned. It does run great without a tune. Been told it will be better after the tune. kids in college so it will have to wait.

I'm not saying they are not worth the money, I think there a great product and you can tune it forever and until you are blue in the face. I would rather put money into hard engine parts. I was looking at the EFI Sniper Quadra Jet style Unit that fits a 70 T/A Shaker with little mods and what I didn't like about it was that it supports up to 500HP only. If I was building something without a iconic Shaker hood and I had the extra cash I might go with one with alot more CFM.

I sold a bunch of parts for a friend. He gave me half of what I received. Plus what I sold off the carb and fuek pump, I only have $100 into the Sniper, fuel line kit and tank in in tank pump.. That's why I changed over to FI.

I just ordered the Fitech 30005 kit. Now I just have to see what I want to do for a pump setup. I do need a new tank and sending unit anyway so if I can find a Canadian supplier I may go with the Fitech and Tanks inc setup Fitech #58018. Shipping and duty cost a lot from Summit in the US

That's a good deal ! You can't buy a stick of gum for a hundred bucks now a days.

Summit needs to put a warehouse in Canada to bypass the duties. Go with the in tank pump.
