New Camshaft question

I had the first ever camshaft failure in this Chevy 402 about a year or so ago. I did everything right by the book. ZDDP paste, high ZDDP break in oil, primed the heck out of it, you name it. I stopped countin at nine wiped lobes and just threw it on the shop floor. Lifters were all junked up too. First wiped cam for me in over forty years of engine building. I'm fixin to bust off a Chevy 283 soon I'm helping a friend with. Melling cam, lifters and timing set. A high end Melling timing set. Yeah they actually make one. I'm bitin my nails, but ultimately, I have a good feelin about this one.
