a lil help with 67 conversion

[67txcamaro]

i bought a 5.3L( the junk yard sd it came out of a 04/05 truck) thinking it was the best route to go. so im second guessing myself. But here is the question.

i thought the ls1 intake would bolt right up. that being sd. I noticed that the water pump neck and other hose is ( i think it goes from one side to the other of the block) hitting.= and the alternator bracket is hitting.

So do i have to another water pump?
do i have to buy some type of alternator bracket
i know i have to move the a/c unit ( i thinking im going with the Kwik performance one)
do i have to move the power steering unit.

thank you for the help.
