Don’t think so. The are still available from Summit and Speedway Motors. Also still listed on The Holley web page.

The Atomic is dead, they are just selling what is left on the shelf. The Atomic 2 is basically a Sniper in disguise.


No technical support for the true Atomics.

A friend installed one a couple of years ago on his LS turbo '70 Chevelle and it was quickly obsolete. He pulled it all off and recently installed a Holley Terminator. Crazy how much he spent on the Atomic originally just to have it not supported shortly thereafter.
