I called Megacycle about 2 years ago, wanting to buy a set of these cams.
I just wanted to see what they did.
The simulator software says they produce a pretty high amount of power, but at a pretty high rpm.
They are fairly long duration, because they give the duration numbers at the .040" points, so they are pretty long. I'd put them in the race cam category.
The other problem was that they didn't stock any of them, and they told me that they don't make runs of these very often. In fact they didn't seem like they really wanted to sell me any of these, and I'd have to supply my old cams to be built-up with hard-face, and reground, and they quoted me about $450 to do this.
So, I never got a set of these.
