I would think that this cam would produce a heck of a lopy idle, with duration #s like that. The lift is rather low comparatively speaking. Those numbers seem to be top-rpm friendly. For comparison, my low rpm-high torque cam's specs are

duration - 194I/204E at .050
valve lift - .464I/.490E
lobe centerline - 110 degrees

This cam gives a very smooth idle on a 292 (or so I've been told, mine is together but have yet to be fired). But I'm only concerned with off-the-line torque. I'd be interested in knowing how yours runs once you get everything together. What's the lobe center angle?
