Good quality stuff - I can't wait to start the install. Get ready for a whole slew of dumb questions.

I have a two pulley adapter on the V8 crank. I know I have to swap to a three pulley adapter... but what runs what?
I'll have the following accessories to run:
Power steering pump
Alternator
Compressor
Water pump/fan
I'm thinking from rear to front:
One belt for power steering pump only.
One belt for Water pump/fan and Alternator.
One belt for Water pump/fan and Compressor.
Sound about right?
The Old Air components are very well made, and everything is mounting up real easy so far... but the instructions are pretty weak.
Thanks

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Feb 2000 Posts: 364 Shop Shark | | Shop Shark Joined: Feb 2000 Posts: 364 | I assume you have a SB ...rather than mess around with all those belts...why don't you consider picking up a late model GM serpentine system at a junk yard. For about $100-200. you can make your life much simpler.(I installed an Old Air in my truck and the serpentine system saved me substantial time and aggravation). | | | | | Joined: Jun 2004 Posts: 15 Member | | Member Joined: Jun 2004 Posts: 15 | Serpentine would be cool, but I don't want to drop any more dimes on hardware.
I think you guys misunderstood my question.
What I'm asking, is what is what belts run what accessory in a standard early 70's SB three belt system?
As in: Rear belt, middle belt, front belt.
Thanks
