pulleys rubbing

Hi guys,
Motor is 451 stroker B block. Problem is wp pulley and crank pulley are rubbing. What is the best way to correct this. Need to remove about 1/16 inch (.060) more or less from wp pulley diameter. Has anyone else been able to solve this problem. Car is nearly complete (69 Barracuda) and now this- grrrr.
Thanks a fishload!
