Comp Cam/lifter failure

I have only used the mopar performance cams. 1st was a 280 then went straight to the 292 purple cam. Never any cam or lifter related issues. Funny how in the past people here would say how bad mopar cams were. If only they were still readily affordable!
I've always liked them. They've never been as affordable as anything else, but I've never had one go bad. I'd LOVE to find a .528 cam for my next slant 6 build. FAT chance. lol
