Personally, I don't know why you'd want to rev an H-D motor much past the 4k mark (let alone 4500 or beyond) before shifting and you'd be pushing 100 mph or so, cruising in 6th in that rpm range. Truth is, there just aren't that many bolt-in/stand-alone cams that hold on much past the 4500 rpm range (for the reasons I stated above) without additional engine work. That being said, you might want to look at something like the S&S 585 cam. It's rated to perform well between 3 & 6k, but the trade-off is that you don't get quite as much torque & hp as grinds rated for lower rpms.
I agree that you'll get much better advice from the tech forums here or over at the Harley Tech Talk forums...

I really like the performance I get from the Andrews 26H's I have in my 103 build. Real World power for me is when I whack the throttle wide open at 1,500 RPM. This is where this build definitely delivers. There are bikes that make more on a Dyno, and from a standing start they are definitely impressive . . . but once rolling on the street they have to downshift to keep up with me, and by the time they release the clutch after their downshift I'm l-o-n-g gone.
