IMHO, I would avoid Comp Cams like the plague.......
They have consistant QA issues that are cyclic amongst their product lines....ranging from cams, valves, springs, etc. Comp is a mass production (McDonald's type) company which - seems to have experience more cam lobe failures than most and places the blame on the low ZDDP in the oils...then experiences valve spring failure, and it just does a cycle. With regards to their cams billets, I highly suspect that they are also using Chinese & they do not include Parkerizing their cams unless you want to pay extra for it (Parkerizing is the final step and a crucial step to help break the cam in- a heated acid bath that microscopically etches the metal surface and adds a very thin layer of graphite coating which allows the cam lube to hang onto and penetrate into the cam surface during cam break in) unless you specifically request and pay additional money for it......if you keep it I hope you paid the additional $ for the Tx.
Considering the cam has such critical importance to the engines performance and life, to me it makes sense to use a cam grinder who will talk with you directly- even modify the cam grind to fit your needs even better and to address the possibility of cam lobe failure with the new oils. When it comes to making an engine breathe, there are so many variables including elevation, humidity, fuel blends/available octane, most cam mfgs will vary a "core grind pattern" to match the external impactors in addition to the internal impactors- which today IMHO makes the different between and engine that runs well, to one that just seems to run a little bit better, smoother and gets better mileage than expected.
With regards to price...the difference is nil- especially considering its cheap insurance to know exactly who is machining such a critical part for your engine. And remember, advertized lift/duration/lobe separation is just that- advertized and not the specific grind including ramp profile that is used on the cam. I highly recommend Iskenderian (who I personally know to this day physically tests/inspects every single valve spring before it leaves the shop) & Crower & Chet Herbert & Lunati...all are family owned, been grinding cams for decades, and both will even re-grind your oem cam if possible- saving you even more $. Also Crower & Chet Herbert & Lunati are excellent names as well.
