if you have the C4AE-E balancer with pulley it should be about 6.625 from top of pulley ear to top of pulley ear.
the WP pulley i don't have a PN for but its about 7.3 diameter, and depth from outer face to center of the pulley groove is 2.00 inches

you can use one from any 390 or 360 truck and they will work, there are a variety of diameters.
the smaller diameter may give you issues at idle with water flow......see the complaints on smaller aftermarket ones........
