Would this cam require tuning or could I drive it for awhile without tuning. I just want a little more torque down low. May put a 3000 converter in a little later also.

 

that cam will not give you better torque down low.....you will have to stay with a 200/200 499/499 114 to get better low end torque than the factory cam

 

That is a decent cam. It is the one I currently have in mine. I would definitely recommend going to the next size up. With either cam you will lose some low end (like Yelo said), but the gains will be very noticeable. I drove on mine for quite a while before getting it tuned which made even more of an improvement. The idle will be kinda bad, but not undriveable. It felt like a loose plug wire to me.
