440 hp with stock block?

Its mainly going to be a strip car. Thats what i expected to hear i just needed it set in stone i guess. Well im going to start looking for blocks. Where can i get them? I know mancini does hemi blocks but what about the 440 block? Im glad i know my options now i wanted something reliable that i can run every weekend. I will be doing a small build for now just to freshen her up while the monster is being built. THANKS AGAIN
