It is a misprint. A better cam, if you're looking for cheap, is a used LS7 cam. Same exact specs, just on a 120 lsa vs the ZR1's 122.5. The narrower lsa will be better whether you're blown or n/a.

That massive of a split and the 122 lsa, i bet that cam is a complete dog out of boost. Personally i would want it on 112 that way boost builds quicker and you could spin it higher due to the increased overlap.
