I often wonder if many of these failed cams users actually take the time to clean/check lifter bores, make sure they will slip though the bores and actually spin on the cam, the basic stuff needed. I noticed for a while some even included some paperwork on the most basic stuff.

Ive used some of the more aggressive lobe comp solid cams and never an issue with just making sure the basic things are "ok".

I know I see many engine assemblers on you tube who could do a whole lot better and makes me wonder how there junk can even run past break in. Simple things in from the machine shop bag to the stand, zero cleaning. Parts straight from the mfg. boxes to the block. No checking, no cleaning. Lifters straight from the box to the block... to me it no wonder some things fail. The the guys who toss a crank in and you see there fingers and arms strain just to get the crank to turn in the block..... super.

I know its not all the end user but I wonder about many are.
