Corral.net is the Mustang site I spend most of my time on. You will learn, from being on that site for any amount of time, that Jay Allen of Camshaft Innovations (
www.camshaftinnovations.com) is an experienced engine builder. Tell him your goals and he will tell you everything you need and he will also custom grind a cam to suit your needs perfectly.
He has made many cams for many people on that site and they will ALL vouch for his ability to make what YOU want.
