Has anyone read Vizard's cam design article in the July 2006 edition of PHR? The concepts are intriguing.

I'm helping my dad select a solid lifter cam for a street/strip '66 fairlane powered by an FE 428. If I use the recommendations in the article, I come up with the following:

Advertised duration between 280-290 degrees
Lobe separation angle between 103 and 104 degrees.

Idle quality isn't much of an issue in our application. However, installing a cam with a 104 separation and that much duration just seems wrong. I'm curious if it would even idle below 1,500 rpm.

Any thoughts?

Yah it will idle fine @800-900 if your talking advertised duration? A little choppy(alot actually) . You will probably need to have a cam specially ground. i dont think i have ever seen a 103 lc in any catalog??
With that spec cam it should pull real sharply and run out quickly!! great for a heavy drag car imo.
