Nothing wrong with them if you pick up the correct grind for your combo.

Legendary name there. They have been around for a while.
They will custom grind a cam if you wish.
I have heard good things from those that used them.

Stripping an engine down & cleaning it out ain't much fun especially when there was nothing wrong with it before, sort of puts one off buying a particular product again

I know, and there's nothing wrong with that, but is it really, really the camshafts fault? Usually camlobes only go flat if the lifter stops rotating. There may be several reasons for that. There may be something that prevents the lifter from rotating, it can only be there for a while, but when the cam begins to wear, it will eat itself up. The cam may be ground wrong, not enough taper in the lobes. Should be able to measure that from the lobes still good. The lifter bottom contours may be wrong, that's harder to figure out, since the bottoms of those lifter are ground as well. If it were a hardness or material thing, there really should be problems in all lobes. It may also be because of incorrect valve spring pressures, coil bind or retianer too close to teh guide. I, and most of people that have run numerous cams, have had lobes go flat, and it really has happened with several different, good reputation, brands. Sometimes it just happens. (BTW, I have never cleaned the engine because of a cam failure, just changed teh oil and filter, and it has not caused me any trouble. -this is not a recommendation, just a notice)

Yes I'm aware of all this, built countless engines & I know you mean well by saying this, though I must bring up the point that I'm very fussy & everything is checked over & over again, things like having a friend turn the cam over by hand ( with fully lubed lifters / lobes ) in the block & applying pressure ( with thumb not valve springs, LOL! ) on the lifter with the pushrod watching / checking lifter rotation etc, anyway to cut a long story short it was component failure

I'm cleaning the engine for peace of mind

When on the other side is peace of mind, and the other side lazyness,...well I have had no trouble making my choices
One year I used MP 296/.557" cams, and wiped three of them. Had a slightly smaller comp cams spare cam that I always threw in with mixed lifters, while waiting for a new cam. That one never showed any wear. Anyway, after the third one I got tires, and switched to a roller. Never really cared to find out what was the real reason for those cams to wipe out. The springs etc. Were also MP parts meant for that cam. One thing I forgot to say, what might be the reason for lobe failures is the accuracy of teh lifter hole angles & locations, and the use of the new less forgicing fast ramp cams.

I've done some things in the past that's considered a no, no, with an engine ( financial reasons at the time, cheap short cuts, LOL! ) & nothing happened, engine ran fine, though when things do go wrong in an engine it's not a very forgiving environment & expensive, so I go for the engine clean option, a lot of work I know

It is never teh cams fault

I did order a Engle cam though, they are ground for the wider lifters too!

Question

Back on the "Lunati" question, anyone have experience or heard of the performance of the newer "Voodoo" grinds? I'm eyeballing one for my 340 project.

Doesn't Lunati use basically a chevy grind in a dodge? I would make sure you add a zinc additive to the oil, and a phosphate something too, you can get it in STP oil additive, they stopped putting that stuff in oil a few years ago as it will screw with the cat converter, notice that all new cars are roller cams now, rollers dont need the zinc and phosphate that was only in there to help a flat tappet survive. I have never had a cam go bad, and I have always used stp, makes sense to me. I dont believe I was just lucky this time.
