Installed on a '79 Bronco w/a 351M/400. I live in Alaska. I can now go thru mountain passes in excess of 5000 ft. whereas before 3000-3600 ft. was the max my Holley carb could handle. From summer to frighteningly cold Alaskan winters, it has been flawless. I can literally go where I've never gone before.
@@armygreenfj3924 I never had a problem with it. I had sold the Bronco years before I posted the comment. The system I had was the original MSD system. They (MSD) were bought by Holley and the current Atomic system is different, so . . ???
Hey Steve, I had my mechanic install an Atomic MSD EFI on my tricked out '79 Chevy C10 Silverado and I could not be happier. What I wanted to mention to you is that because my truck has dual fuel tanks it made the installation more complicated. My mechanic had to fabricate a cylinder shaped fuel tank, about quart sized because when one of my fuel tanks went below half a tank I could not get enough fuel to my engine and it would die out. That's the best way to describe it from a layman's perspective because even though I've done a lot of work on my engine, I considered this job beyond my skill level and tool availability (and because I'm an old geezer now I prefer to have other people do the hard work). I'd had it with other people's 30 year old rebuilt carburetors, and in California, new carburetors are not street legal as they will not pass smog. With my carburetor I had to pump my accelerator like 12 times (sometimes more) to start my engine when it was cold. To make matters worse it would sometimes die on me when starting out from a red light. That made me as nervous as a long tailed cat in a room full of rocking chairs. It's very embarrassing to have a really nice looking truck that doesn't run. Also, after I did drive it and I'd come home, my carb would drip fuel filling my garage with the smell of gas. I was afraid my wife would shoot me if I didn't get it fixed. Now, I'm as happy as a pig in mud. My truck never dies out, runs as smooth as silk, and I get better fuel mileage from the 350 cubic inch. Thanks for the excellent video.
I already have fuel injection an outdated pro flow. Can this system be used with my existing return style fuel system. And will it work with a hall effect switch in the dizzy using the 6A to control timing?
The separate computer unit is actually why I'm going to end up buying the atomic one over the atomic 2 they act like it being all in one is a good thing but the heat can Fry out the computer and cause major problems
Having rubber hose from the fuel pump to the front of the car will cause a rough idle because the hose will pulse when the injectors fire at an idle. Mine does. Grab the rubber hose at an idle and you will feel it pulsing like a heartbeat,,,,,, bad
The Atomic has five vacuum ports, ported and manifold, to cover accessories such as a power brake booster (Figure 3). Four ports are 1/8" NPT and one is 1/4" NPT.
The post filter is Holley part 562-1 and is designed specifically for the Sniper EFI kit. It does not have a specific rating but should be good for up to 60 psi.

Thank you for watching and the feedback!
Great info, This guy is good he sold me on this setup
I already have fuel injection an outdated pro flow. Can this system be used with my existing return style fuel system. And will it work with a hall effect switch in the dizzy using the 6A to control timing?
Real nice vid....question is it possible to adjust the fuel to the injectors to 70 psi while idling
I'm in the UK and have the Atomic EFI... We've just gone over to e10 fuel. That's 10% ethanol vice 5%... It the Atomic fuel hose ethanol proof?
Will this work with the edelbrock sump pump instead of using the fuel pump from msd?
I am installing a fuel tank with internal fuel pump/sender unit. Will this system work with this set up?
Is there a fuel pump relay somewhere? Or do I need to wire one in? Thanks!
I have all brandie lines #8 any chance the kit comes with those fittings to work and ports for unit for power brakes
I have a Lincoln mark v 6.6 litter that I want to convert help.
The separate computer unit is actually why I'm going to end up buying the atomic one over the atomic 2 they act like it being all in one is a good thing but the heat can Fry out the computer and cause major problems
Will the help fuel economy
Can you run 2x Oxy sensors?? one in each bank?
Madmikescustomdaily says so this amazing video

At 4 min 44sec it is stated that if I am opting for the return-less set up its preferable to be ran with the pump in tank... is this correct? Thanks
I've done it with the pump externally mounted like he shows and using a return line and it's perfect.
I need a pump mounting bracket like that
If installing into a factory Big Block car can I just use existing 3/8 fuel line?
Yes
What about spread boar?
You will need an adapter plate from a spread war to square bore it will work just fine
Is there a vacuum port for a HEI distributor

His voice is made for these vids. lol
How does this system compare to the FI Tech?
Very simple, and imo it learns better.
No Vacuum ports ?
Why no ports for vacuum in kit would be nice and can u put in 8# fittings instead of 6
What is the psi for the post filter?

My God I wanna do this to my 76 buick skylark
This is awesome
Can this be used with turbo applications?
I'd call them and ask if you can replace injectors/drive more of them because two injectors arent gonna cutit
stlmikie ,
The atomic is designed to be used on naturally aspirated motors!
BTDT Yes it's that simple.👍
Steve, thanks for pronouncing your name correctly, and not Americanized. 😎
EL PASO, TEXAS!!!!!!!!!!!!!
this system is shitty burns raw fuel even with all adjustments ,FAST efi is a lot better
Ya easy non typical install. Try a 1977 Chevy k10 4x4 with low pressure dual tanks....
I would put the pump after the splitter to keep use of both tanks.
Exactly. Pump after splitter.
I don’t have catalytic converters
Nobody else does either
DO NOT BUY FI TECH!!?...i put a new motor in my truck less than 18 months ago and eci going bad !!....truck cut off going down I95 !!...
not good...save yer money for another brand.
