That or someone told him they were great cams with no comment regarding the RPM range and he didn't like them because they fall off around 5000.

 

I assumed most of your riding is without a passenger and more spirited than the way I ride. I like the 551 cam because almost all of my riding is between 2,000 and 3,000 rpm and with a twitch of the wrist climbs steep hills without down shifting. The downside is going through the gears when riding alone is in my opinion lacking. That is why I think the 48 would be a better fit for a street glide.

 

You don't say what year your bike is. If it's a Rushmore, my first choice would be the CR 570's for the most torque on a stock engine.
