Several fundamental problems here.
No overlap data given AT ALL, and thats pretty critical on a blown motor.
No details given of at how much lift the duration is measured
You havent said anything about the engine, like what RPM band it will be working in etc.
Fundamentally, assuming (BIG assumption!) all other things are equal about those two cams, the bottom one will pull better low down and the top one will be better higher up the rev range.
Cam choice comes down to so much more than you have specified there though and is very dependant on the spec of the rest of the engine.
Is it an RST motor? (you said CAM not CAMS)
