I'd check with the cam mfg's - they're the experts. Tell them what you want in the way of engine characteristics and performance. I'd try
www.compcams.com, www.lunaticams.com (or Holley site, they own Lunati) or
www.cranecams.com Crane & Lunati have lots of Ford experience, and have pretty good descriptions of their cam's operating characteristics in the online catalogues.
