I have 10,000 miles on a xe262 with no problems. I changed intakes a week ago and checked the lobes while it was off. They looked fine.
I just pulled another 262 from an engine that had a wrist pin back out at 600 miles. The cam was fine.

PRESSURERAT, good reply I am not sure myself who is at fault here just trying to add another view of the situation. A bad company is going to deny anything is wrong, try to cover it up etc. etc. They would also probabaly blame it on you and not refund your money. I am not seeing this. If it was the XE was a problem with agressive ramps then wouldn't most of them fail ? I see a few failures but the majority seem to be going strong, this leads me to operator error not a production problem.
My main point is that I think the CC XE cam seems to be the most widely used cam in small blocks these days especially here on this forum. I am wondering if the Magnum series were more popular we would not be seeing more failures in that line

I got 4 months out of my xe268 and roughly about 5,000 miles, and then it wiped a lobe. I'm not really sure what caused it to wipe the lobe. I dropped in a completely different motor afterward anyways. This topic has sparked my interest though, so i think in the near future i'll try another company's cam and see what happens. At worst i'd be out a couple hundred bucks and a few hours of my labor. But this would also mean I have to find another car to drop this motor into

I broke in my XS268S (solid lifter version of XE) in my BB in early July. I used the recommended dual springs (left the inners out for break in) and have logged about 1800 miles so far. I used the Comp Cams lube on install, but turned the engine over on the stand only to see most dripped off. I then coated the lobes with a moly cam lube I got from Napa I think. It was much thicker and stayed put. At this early stage, I haven't noticed anything to get me nervous. I hope it stays that way.

Voted other as I found my stock Chevy cam with #4 exh lobe wiped on my LM1 GM goodwrench 350. Guess the previous owner had the new crate motor installed <30K mi before me. I got the reciept and will never patronize that corvette shop.

It's posts like these that make me nervous to "get on it" now. Not that I would rather be ignorant on the subject, just wish now I had put in a different cam. Now I'm just waiting to begin feeling/hearing the signs of a telltale wiped lobe. And those are....?

Is it true you should not be using 1.6 ratio rockers with a XE268 cam?
Is that an increase or decrease in idle speed?

Okay just went out and started it. I have an audible ticking, but it is coming from where the headers meet the cylinder head. And it's just on one side. It doesn't sound metalic, more like exhaust, but I could be wrong.

Lots of tracking, all around the gasket, I am hoping it's exhaust. I have to change to metal gaskets.
Thanks
