How do hydraulic flat tappet lifters fail?

Righty, I'm sorry this happened to you. Every winter I think of changing to that cam in my stock eddy headed short block 360. Then I see this post. I work on heavy equipment, the parts for everything are made like junk now for lack of a better term. I'm gonna keep my 204/216 crane. Good luck, keep us posted!
Thanks for the sympathy! I definitely wasn’t pleased to have this happen. But before you discount the Lunati Voodoo, keep in mind that there’s a high likelihood that it failed from a botched break-in, not from poor workmanship or metallurgy (although the metallurgy part is up for debate in my opinion regarding the lifter). All that being said, this was my first rebuild, and I don’t know if you have read my previous posts in the thread, but the timing was off and it took a bit more cranking than is healthy for it to get her started. I will certainly keep y’all abreast of the progress to come.
