    Manufacturer's Part Number:

    The all new Atomic EFI system was designed with two goals: simplicity and performance. Simplicity was achieved when MSD rewrote the industry standard for easy installation and programming. Performance is served through improved drivability from idle to full throttle blasts. The MSD Atomic EFI can be installed with basic hand tools in just a weekend! In fact with little preparation, installation can be started on Saturday morning and the car will make a cruise that night. This is due in large part to the ability to run a returnless fuel system so there are no modifications to the tank and no need to run another fuel line (in most applications). MSD incorporated the ECU into the throttle body to reduce the wiring and connections. MSD also moved the four main sensors inside the ECU for even less under hood clutter and wiring. The Atomic EFI comes with a compact handheld monitor that allows you to select a number of parameters to match your engine combination. This will get the engine to fire up and it will start learning your combination immediately. No software programs to learn, and certainly no jets or idle mixture screws. In the end the Atomic EFI delivers the performance and drivability expected from an EFI yet with an installation so easy you'll have the rest of the weekend to cruise.

    Frequently Asked Questions

  • 2900 - MSD Atomic EFI is rated 3.6 out of 5 by 7.
    Rated 5 out of 5 by from So good I'm going to buy it twice I recently installed this unit on my 1962 GMC pickup with the original 305ci V6 engine. The kit installed so easily it was like it wanted to be there. After tinkering with the A/F Ratio settings and other parameters, my truck is running better than I thought it could. That old engine used to run out of steam around 60mph (probably because I could never get it tuned right with a carburetor) and now it cruises right up to 100mph before I even realize it. The kit is so good, I'm going to buy one for my 1968 Impala.

    Rated 5 out of 5 by from Excellent system The atomic EFI system is excellent and I am very pleased at how easy it was to install.I just finished installing the system and it runs great.All I have left is to drive it and a few detailing items.I think I will be very happy once I am totally finished.I am already happy with the way it starts in cold weather.With a carburetor I had starting problems and I was not happy with it.Can't say enough about this system.Thanks.

    Rated 4 out of 5 by from Good product but pricey First let me say this is a well-made product easy setup plug and play system. That being said the major reason for buying this over the other competitor’s EFI systems is purely compatibility with the other MSD items I have on my truck. My 383 is street able @ a little over 500hp but if you’re thinking of building up from 650hp and over forget it. MSD will not handle it now but wait with technology changing they’ll build something to keep up. Again good made product but to pricey for the HP. Shop for the EFI that meets your needs there are less expensive ones. And I bought this from Jegs because SUM&^# customer service stinks.

    Rated 4 out of 5 by from Great way to convert to fuel injection I bought this item when it was on sale a few months ago. Installing it was straight forward. The manual is easy to understand and any questions I had were answered by knowledgeable Techs on the phone. I have not yet driven the car ('63 Thunderbird) as it is now winter. The engine runs good in the shop. I am anticipating a good season of trouble free driving.

    Rated 2 out of 5 by from Inconsistant I had a certified mechanic install the MSD Atomic on my brand new 383 crate motor. Some days it works well. Other days it will stall and bog down. Paid a lot of money for this and I am sorry to say I am disappointed.

    Rated 1 out of 5 by from Junk Junk Junk Not completely a simple plug and play! Have been on the Hone with MSD techs several times. I am meet with rudeness every time I call. They walk me through setting final adjustments. Car runs great.... then next day it's all scrambled and car runs horrible. I am running the non return option and I believe that's where the issues are coming from? But they advertise it will operate set up this way.

    I have an 82 K5 Blazer with full smog appliances (Cali Car). With this being a CARB legal kit, what can I eliminate off the manifold? Lots of vacuum hoses to the carb, EGR valve etc.

    Asked by: Mboom
    If you want to remain California legal you would need to retain all those items

    Will this kit work on a 1979 Ford F-250 6.6Lt 400cid? The engine has an Edelbrock performer intake, mild street/strip cam, MSD 6AL controller and MSD distributor w/o vacuum advance.

    Asked by: 79F250

    Plan on building a 5.3l ls engine and running the carb intake with msd controller box. I will have a 700r4 trans behind it and more than likely put it in a 92 chevy c 1500. I like the simple wiring and did not want to cut and splice wires all day.

    Asked by: 3Wood
    Hello, If you are asking if this will work with that app, yes it will work with that 5.3.

    Will this system work with a 1977 Chevy stock 454? And which MSD distributor is recommended to work with this system and my engine?

    Asked by: Slow Roll 77
    This system would be compatible with your vehicle. An MSD 8360 distributor would also be needed.

    Will this kit handle a COMP Cams 12-601-4 Part Number: 249-12-601-4 camshaft in a sbc?

    Asked by: shawn1970
    No, you would be better off looking at an fitech system, it can pretty much handle any cam size.
