I had a double water pump pulley on the 305 and the AC went on the second puley so you 3 row it should be on the middle pully not the outter 3rd one.

Here is the correct belt line up for a small block.

Outside belt is crank and power steering. Middle belt is crank water pump and AC. Inner belt is water, crank and alternator.
