Usually with the 6-71 871 style blowers and drive setups there is no pulley provision for air conditioning.
The SBC kits use a short style water pump.
If you were to integrate more pulleys behind the crank blower pulley you would need to space out the top blower pulley. This will put more stress on the engine's front crankshaft main bearing. Its bad enough already.
And more stress on the blower drive snout bearing.
All these blower drive kits should have been upgraded to the newer flat belt style alternator/water pump pulleys.
much better than the Vbelts and V groove pulleys.
