There is a company that the author of Under Pressure column used to design his cam for his 331 1000+HP turbo motor. The did a small article on it, & remember it specifically but can't find the issue...
I have the article saved, but I'm out of town. That's the one about Denny Wycoff of Arizona Speed & Marine (right?) picking cams from off the shelf that most closely match his custom cam specifying "Cam Master" program.
