I know Kevin will love this, and I bet a bunch of others will enjoy it too. It's long, and if you click on a figure in the article, a new window with all the figures and captions shows up.

Kevin, he's talking about the slider-crank thing, but only touches on the details.
BTW, I found this by doing a google search on "camshaft selection" (I know, I take FOREVER to make decisions ). Here's the link to what it brought up on Vizard's site:

Vizard offers a service for selecting the optimum cam for your use. Interesting that he mentions the same shop in Tucson AZ that Thurem noted in a post yesterday. I wonder if they still will run your numbers if you call, as Vizard charges $35US to select your cam with the software he wrote and they beta tested.
BTW, he notes that the cam companies will tell you different things every time you call. I had just that experience lately.
Anyway, the High Compression article is very interesting and has a bunch of good info on Intake valve closing and compression ratio, like Kevin has shown us many times.
