Go with the cams these guys are suggesting and set the idle speed at about 500 rpms. That's as close as you are going to get to a nice choppy idle without drasticlly affecting your cars performance.
This reminds me of a good friend of mine who was in the right place at the right time when he bought his first car. He bought an early 70's challenger with a 440 that dyno'd 500 HP at the crank for I believe $1500-$2000 about 12 years ago. The car was a little rough, but had a decent paint job. Anyway, this thing was quick, one of the quickest cars around amongst the teenage crowd, but it idled smooth as glass at 900-1000 rpms, so he wound up always driving around with the idle at about 600 rpm just so it would sound tough at idle. This was the last car that needed to sound tough, because it was. He had plenty of power but it was his first car, and it wasn't right to him without the rough idle.
