What cam should I get?

Something else to consider. Cam catalog listings group all small blocks together. If you havnt installed a bunch of cams, you may not know the down sides of using one that's too big. The 284 MP cam in a 360, with a bigger bore and more importantly a longer stroke, will have a note at idle, and will feel a little soft unless the engine has decent compression. The same list has the 284 as fitting a 273. It will be a bear to do aything with. The bore is smaller, and the stroke is shorter. You have a small engine. That means a medium size cam on a catalog list acts like a large cam. I've run the Magnum 268 cam before. In a 318 with low compression (bigger port heads) and a 340 with 9.8:1. It has what you want for a noticable idle. But it will not be the best from idle to about 2800. in fact, it may be hard to tune to not feel like a dog under 2K, where you spend a bit of time cruising now. I think the XE262 would be a good choice, but I think your idle will be better than you may want. Why you want a bad idle, I have no idea. For those that "know", a bad idle means you either cant tune it, or assemble a decent engine package.
