360 Engine Cam Choice

I have a bone stock rebuilt 360 engine (out of a 1985 Dodge Van) that I installed a dual plane Edelbrock aluminum manifold and 4 bbl. carb on and I am putting in a 1972 Dart Swinger and I want to change the camshaft to give the engine a nice "lope" when I drive it to car shows. I am not concerned with performance or horsepower as this car will never see a race track. I just want a healthy lope without having to use a vacuum canister for the power brakes or having to change the rocker arms, push rods or lifters. Any suggestions as to lift/duration would be appreciated.
