You seem awfully upset about this, not sure why.
I also stated the SRT cam was better, but offered an alternate possibility as to the reason for the accelerated failure for "some" non-srt cams. If I missed something and somewhere someone said "all" cams from certain years fail, well then so be it. That still doesn't account for the fact that only one part of the equation is completely constant and that's the design of the block and oiling. The cam/lifter material will NOT (likely) be consistent for a span of years. Something would change.
I don't think anyone is arguing against the cams failing, but other than your visual inspection, you offer no other explanation other than "it's a crappy" casting... I find it hard to believe the Chrysler (Daimler) engineers wouldn't be able to figure that out and have it fixed. I supose I could be wrong, but correcting an alloy for the casting would be a helluva lot cheaper the warranty work. I also find it hard to take anyone serious who doesn't offer up a real explanation and they gets upset when people don't just say "Okie doke...". Clearly enough people aren't satisfied with that mode of thought, not just me...
In the end, I'm not arguing. You build engines it seems for a living, or something... I don't. Best of luck to you. Maybe you're right, maybe not. I suspect this, or your post, won't end the conversation about the cams failing though.
Cheers.
