On a 1974 360 with AC and power Steering, Does the crank pulley only drive the power steering pump? Currently I have a Vintage air conditioner. The crank pulley turns the alternator and the compressor. The crank pulley drives the water pump and the power steering pump. The Vintage air diagrams show that only the PS is driven off the crank pulley. Since that is the way I purchased the engine, I wasn't sure if the pulleys were set up correctly.
