A stock type radiator should do the trick, I know lots of people using them with 350's and they don't overheat, you may have another problem, do you still have a good air deflector under the front end? It deflects most of the air into the radiator. And usually a 3 or 4 row radiator will not cool any better than a 1 or 2 row because by the time the air passes the first row or two it's already heated as hot as it's going to get and the last row or two don't do anything, if you really want a better radiator get a aluminum unit with aluminum end tanks, several company make them to bolt into Camaros but they cost a pretty penny.
