twitchy steering

I have rebuilt the complete front end of my car -I'm using a 73+ front disc setup, used all Moog parts, edelbrock shocks, big block t-bars. I have had it aligned by supposed persons that know how, but driving it down the road and hitting any small grooves,ruts or inperfections in the road seem to make it go all over the place-no single hand steering. I dont know if this would be consider bump-steer. The car does have the quick ratio power steering which I think make it feel worse. Would this be an alignment issue or something else I'm missing?
