318 pulley mistake, need the correct size.

Thank you, but I still need to find the correct water pump pulley size for a factory ac car. I will need to look for used parts, these new ones cost a lot of ca$h.


Screw all that. Use the biggest crank pulley and the smallest water pump pulley and a high flow pump.

You’ll be able to drive through downtown hell and hit every light and still stay at thermostat opening.
