I have an old print out I was able to print off the internet. Try a search engine and ask for H-D camshaft Specs. The Andrews 21 has a intake duration of 220 and the exhaust duration is 228 and it has a 0.498 lift on itake and exhaust.

I LIKE CHOPPER USED A EV-27 CAM and like that in my LIGHTER BIKE....
I think the LOWER #ed cams are for the SLEDS and a LIGHTER bike like the FXR is in need of MORE lift and duration cam..
look at NIGHT RIDER(google) and see other builds with EVO motors..
