1981 Chevy Truck V8 Two Wheel Drive Automatic

I have an '81 Chevy C10 with a 350 crate motor replaced by the previous owner about 60,000 miles ago. The truck starts hard sometimes whether it is cold or hot. Pumping the gas helps some, but not always. What can I do to resolve this?

I have replaced plugs, wires, distributor cap, PCV, air filter, as part of a tune up since I didn't know what shape the engine was in, even though it only has 60,000 miles on it.
