Using that in my BB now.
Thought I was being frugal keeping my stock TC with that cam.
Now I know I was being stupid.
Get my drift?
TC?

That cam ran great until it went flat. TWICE ! I have a 493 in my 70 Charger, Edelbrock heads, 2" TTI headers and an Edelbrock performer RPM intake. The XE285 ran better than the '509 MP cam and gave a smoother idle, but after 450 miles, it lost an intake lobe. I pulled it and slipped in another. That one lasted about 1500 miles. YES I performed proper break in procedures and used The approved oil additives. I douched the motor out and put the USED 292/509 cam back in with new lifters. It runs great again and so far , every lobe is still hanging on. I dont know if I somehow had crappy luck TWICE in a row or what. I would try another Comp Cams product again, but next time I will try their PRO PLASMA treatment. Their ads claim that it increases the durability.
sounds like it may be a lifter bore issue with the high rate cam, kinda like the moparts enginemaster motor had

I've used two of them, and I've liked both of them (I've used the .545" and .564" lift grinds). They are very noisy cams though, I think due to how quickly they open/close the valves (and, no, I don't have any weird lifter/rocker issues). Try one of 'em out!

I run a XE268 in one of my 318s. Decent low end, but makes most of its power at mid and high range and will wind up. Not too radical, nice, mean idle. I like the cam. They are noisy, though, especially when cold and when at a consistant RPM, like 2000-2700 rpm.

XE295HL......IMHO about the best all-around cam for a 500" stroker street engine.
Brutal mid range torque. 
Thats the one i have in my stroker. I havnt fired it up yet, so i have no worthwhile advice, but it sounded like the way to go when i bought it.

They make noise You hear it---it is there On the dyno they do crazy stuff--One RPM great --next level RPM goes weird--overall you are getting what the computer says works and graphs out right--in the real world you get a lobe that is using every mm of the lifter adding to the chance that you will have cam/lobe/wear issues--the real ADVANTAGE to a Mopar .904 lifter is that we had way more diameter than GM and Ford so we had a sort of "mushroom" lifter but with lobes made to take ( for computed figures sake ) the entire diameter--we gain on paper but not so much in the real world and we GIVE away the BEST advantage a Mopar has. Just my BS opinion but I have built more than one

What kind of rpms are you guys getting out of the 285 and 295hl? I've read some guys say the hi-rate of lift cams like these tend to fall off above 5000.  Will they do 6k or 6500?
Was shifting at 5900 and trapping at 6300.
That was with the XE295HL. Certainly didn't "fall off"!!!

I ran the 285 cam in the 493 in my Charger. Great sound, great power.....BUT both wiped cam lobes even with careful prep and break in. The second cam was actually over the top as far as installation, cam lube, break in additives and Royal Purple oil. STILL with box stock Eddy heads and springs, FAIL. I deferred to the Mopar 509. It makes less power, but it still has all 16 lobes.
My car runs so good though, that I would be surprised that the cam is bad. I just did some more carb adjustments and have it running the best so far. It hauls, plenty of power, torque, but the damn noise.
