power stearing pulley

Got the bracket for the alternator and the pulley taken care of on my 440, but then I went to install the power stearing pump and the pulleys won't line-up. It looks like I need a 3 or 4 groove crank pulley, the one on the motor has only 2, the first one is for the alternator and aligns perfect, but the second one is off by about the thicknes of another pulley. (from the first groove to the second there is a gap about half inch or so) I tried using a 361 pulley which is a 4 groove but only 5 of the crank bolt holes would align, same with a 383 pulley, I imagine that there not ment to be used on a 440. Has anyone ran into this problem while swaping to a big block, is there such a thing as a 4 groove 440 pulley? if so are the holes drilled different? I need some help, please let me know. Thanx, Dart.
