It is not just Comp Cams (I have had too many problems with ALL their stuff to list). I will stick to Crane or small custom cam grinders from now on.
Piper Cams (UK) seems to have more than a few issues with quality control. Not just on the lobes, but also on the cam to drive mounting surfaces.
I will not buy Dart blocks pre-machined ever again. They repeatedly say that their machining is top quality. I beg to differ. When a timing chain will not fit on a block, it IS a machining issue at their end. And they really don't care about the end user.
I will say that several piston manufacturers I have dealt with have made mistakes, but were eager to quickly remedy the situation.
On connecting rods, I have decided it is easier to buy from a couple of more expensive manufacturers than to take the time to correct or return a cheaper company's product. Even if it is just for peace of mind.
It is not about just making mistakes. It should also be about how a company does or does not remedy the situation, and their attitude towards the customer.
