Install Saturday Morning, Make the Cruise Saturday Night with the Atomic Master kit. The Atomic EFI outshines the competition in ease of installation and performance! The MSD annular ring injection design produces an air/fuel charge with much better mixture as well as an even distribution among the cylinders that the competition cannot match. Better AFRs equal better idle quality, better starting, and better overall drivability throughout the rpm range. You and your engine will be glad when you Go Atomic.

This is the complete kit for anyone planning to convert from a carburetor to Atomic EFI. You get the Throttle Body, Power Module (with Wide Band O2 sensor), Handheld Controller, and the Standard Fuel Kit for up to 525hp (at the crank).

  • Bolts to standard 4 barrel intake manifold
  • 8 wire connection installation
  • Replaces standard square bore carburetor
  • Controls ignition timing
  • Integrated ECU and sensors
  • Single fuel line
  • Self-Tuning
  • No Laptop required

Application

The Atomic EFI was designed to bolt on to any square bore, 4-barrel intake. This includes common 4150 and 4160 designs. These intakes can be found on countless engines for muscle cars and hot rods including small and big blocks by Ford, Chevy, and Mopar. There are even aftermarket intake manifolds to convert LS engines.

Notes

The Atomic EFI throttle body is actually so much more than a throttle body! Check out all the callouts on the graphic Atomic EFI Features to see how this throttle body is easier to use.

There is no horsepower advantage to this fuel injection as compared to a 4 barrel carburetor. The advantages are fuel economy, convenience, and minimal maintenance.
