I would go with a 76mm C&L rather then the 73mm Vortech which is a C&L. Check out the Comp Cams XE grinds, they have awesome ramprates and will make great power. Call their tech service and give them your combo they are very good or call Rick Anderson and ask about one of his cams, thats were I went for my custom cam, I have a modified grind of the N-61.
