What's in the Box
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.

ApplicationThe 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.
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.
