Erson cam specs??

Pulled the 340 out of my Dart to clean up the engine and engine bay so thought I would see what cam is in it since previous owner had no idea:thumbdow: Looks like its a hydraulic judging by the lifters but the only details on the end of the cam are "Erson Viking 100H". Anybody have a clue what the specs are on this cam?? I could not find any info on the internet.

Thanks
Derrick
