I have a 350 sbc with a alt. on the passenger side, a/c compressor and power steering pump on the drivers side. The pictures are not great.

Alt pulley- 1 groove
Power steering pulley- 2 groove
Water pump pulley- 1 groove
Crank pulley- 3 groove

Standing in front of the engine.......
The first groove on the crank pulley goes around alt and water pump
The middle groove on crank pulley goes around the first groove on the power steering pump pulley
The rear groove on the crank pulley goes around the second groove on the power steering pump pulley and compressor

Yes, adust the Alt belt first, Power steering belt second and A/C belt last.

I can't see the compressor, but I assume it must be the small R4 compressor. I have an A6 compressor and HD cooling, and the belts and pulleys are set up a little differently. I also don't have the compressor mounted right now, but I think I can remember the routing.

1st (front belt) - same as yours; alt, crank, water pump
2nd - PS, crank, water pump (this is for AC vehicles); in vehicles without AC there is a shorter belt that goes around only the PS and the crank
3rd - crank, PS, AC, like yours

The difference is the 2 groove pulley on the water pump, which I believe is part of the HD cooling package. This puts a 2nd belt on the water pump pulley so that if you lose the alternator belt you will still have the water pump being driven by the crank.

Its the large compressor.
