How about a cam for this engine?

I was going to re-use my Crane cam which came out of this engine for the rebuild. I believe the specs are around 270/280 (advertised duration) with about 494/500 lift, but I have the cam spec card at home and can update this info' later.
I want to stay around 270-280(advertised duration)and 500 lift,
was considering this cam;

Lunati Part # - 10230703
RPM Range - 1800-6200
Duration at .050 - 226/234
Advertised Duration - 271/279
Valve Lift w/ 1.6 Rocker Ratio I/E - .494/.513
LSA/ICL - 110/106

Remember this is for a street driven 1971 440 Challenger with a four speed and 3:23 gears...
