Having installed countless cams most were Comp I would say they make an excellent product. I have had one with a casting issue and the lifter rode only on half a lobe. I had no problems with replacment. I also wiped a lobe on break-in on a 383 I built. I bought the cam through Summit. Summit replaced it no questions asked. It was my fault for being too lazy to remove the inner spring on a triple set-up. If I were to choose a new cam I would have to say Comp, Isky, and Lunati in that order. Just my opinion.

I like Comp's product myself. The only parts of my valvetrain that aren't Comp are the rockers and the lifters. The rockers are Crane and were on the car when I bought it. I couldn't justify not reusing them. The lifters are Crower Cool-Face units. Comp's laser-hole lifters were on backorder and I needed lifters right then. Comp makes quality parts but I think modern oils have given them a bad rap.Brett

Why is it that the lack of zinc in modern lubricants isn’t wiping out the OHCs in the imports? They aren't rollerized either, the lobes actuate followers that operate the valves, without rollers. Are the pressures on the lobes in the American V8s so great compared to the imports?

i think comp cams is a class outfit based on my dealing with them. they have outstanding customer service and tech advice. having said that....i have seen more posts about their cams failing by FAR than anyone else. myself i purchased a cam from them for a sbc, it failed but they were more than fair with me. however like i say the number of posts i have seen about their cams wiping out is almost legendary. it pains me to say it because i really think they are class people but i dont think i would ever buy a cam from them. just my opinion.

These numbers are pulled out of the air, but if you sell 3 times as many cams as anyone else wouldn't you expect to hear 3 times as many horror stories? Even if the failure rate is .0001, if you are that .0001 person then your perceived failure rate is 100%. People with problems tend to be more vocal than satisfied customers. I think Comp would have a hard time maintaining their business if their cam failure rate was much above the industry average.

Wonder if the hardness of the metals is different in the imports, meaning better quality/matched? Im not a metalurgist, but it seems to make sense. I know some of the LT-5 guys have had a lot of problems with a certain cam manufacturer whose product keeps wiping out lifters.
Those are DOHC v8's.

Also, on SBC and BBC the lobe/lifter interface receives ONLY splash lubrication. How is that "wiping motion" lubed in an OHC engine??
