Lunati 703 cam

That sucks but I'm not surprised. Anything manufactured is bound to have a few out of box failures. I lost the first cam in my 340 to guide clearance issues. I have the lifter on my garage wall to remind me to check everything. Was the plunger stuck/jamed in the lifter?

Yes, it was clear down.
The engine was broke in, the lifters were fine on initial start up, and run thru temperature cycle, several times.
Replace the lifter with one Lunati lifter, and the engine is still running.
