The 600 cfm should be about right even on a stock 350, the condition you describe, rich on a steep hill is due to the fuel bowl filling up and spilling over into the airhorn or even getting raw, unatomized gas into the carb passageways. Try a spring loaded needle and seat kit, I will try to find you the edelbrock part number if you will tell me the part number on your carb ie. 1405, 1406 etc?

Personally I think 600 is too small, but I like to go fast too.

Like oldgoat said, the problem you describe is caused by the carb flooding due to the angles.

I had a 1406 on my 400M in my Bronco, changed the needle & seat and it solved the same problem.

the part number is 1465. does the needle and seat make a big difference on the inclines? i have heard that they do and that they dont. what have you guys experienced?

On my 1406 which is the electric choke version of the 1405, the spring loaded needle and seat made a world of difference just like TX_ZUKI said it did for his 400. What is the model number of your carb? If you have a performer series with the spring loaded needle and seat kit it should do well offroad, the others I am not too sure of.
