Its all a big contradiction of terms. Please read and understand this before commenting.

When Custom Cams were discussed, it was at the same time as Karls Custom Cams were also mentioned.

I am lead to believe that you could get Karl to spec you a Cylinder Head, Turbo and consequently a matching CUSTOM cam. This is then be called an NMS Custom Cam. Even though I still believe to this day that Karl doesn't actually grind it (and I don't hold that against him). After all, Cam grinding equipment isnt something you can just pick up on Ebay.

You cannot go to Newman and tell them the spec of your engine and ask them to design you a cam, therefore they cannot supply you with a Custom Cam. They will offer you the one and only CVH Turbo cam that they produce.

You can, however, go to AVA and Alan will spec you a cam, which he will instruct Newman to do. That to me is an AVA cam on the same basis that the one that Karl offers is an NMS cam.

Similarly, I would imagine that Ahmed can do a Cam. You will probably never know who physically made it, but you would refer to it as an Ahmed cam.
