I have an aluminum water pump and crank pulley.. all the pulleys line up good. Don't see many things to adjust to fix this  |
Your pictured setup has the belts reversed from the OE-Factory BBC SWP configuration. When these original 68-72 BBC trucks left the factory the alternator belt rode the inner (closest to engine) groove and headed to the opposite of engine, the AC compressor drive belt originally rode in the next groove forward where your alternator belt is now.
