Axle ratio, compression and converter are all important. Don't mismatch your cam and converter, or you'll be unhappy.
My advice, unless you are willing to take some big steps, leave well enough alone until you are.
For a motor like that I would be inclined to run with an L79 cam(2200-5500 rpm)(Its my favorite mild sbc cam), a 2800 converter, some 3.42's and your all set. As you can see though, you are going to open up every piece of your driveline. You may already have gear though.
Check your glovebox for the rpo codes...look for these
G80(posi) and anything else with G...this will be your gear designation.
