Question about pulleys/AC - The 1947 - Present Chevrolet & GMC Truck Message Board Network

cali_surfer · 08-02-2003, 02:26 PM

I'm doing the Old Air A/C install once the kit arrives but I was wondering a fellow board member could give me a little help on the pulley setup of an A/C truck. My motor is so far from stock, I have a long water pump and alternator on the passenger side. I also have power steering, on the driver side. My question is, what pulley configuration will work with the new A/C compressor? On a 73-87 chevy truck they used the A/C compressor on the driver side correct? If so, how are the belts arranged? I have billet aluminum pulleys rightnow and have no extra grooves available, I have a single groove waterpump and a double groove crank. If anyone has ran into this or could help me out I would definitely appreciate it.

I always say, "Go one way or the other". Either use all of the correct 72 & older swp setup or the 73+ lwp setup. They do not mix well. You always end up cobbling, shimming, miss-matching and wasting time.
