318 pulley mistake, need the correct size.

Update!

Got the pulley and it fits.
Now I think I should get a fan clutch instead of having a fan mechanically bolted to the water pump.

Looks like you have the right setup for your app. HP needs a smaller crank pulley as the accessories need a larger one, to slow down the rotation, so not to overspend at high RPM's. Some even had a cooler at the power steering.
