Default v-belt pulley alignment

i just finished mocking up the front dress on a ford 5.0 engine. i have an frpp (edelbrock) max flow water pump and frpp billet aluminum v-belt horsepower pulleys. i haven't properly installed the water pump yet i.e. gasket to timing cover and torqued down the bolts; but i measured from the face of the damper (torqued properly) to the face of the water pump pulley flange and found the distance to be approx. 3 1/8". i believe the spec is for 3 1/4". with the gaskets installed and everything tightened down, i should move closer to 3 1/4" as required.

so my question is, what is the tolerance for proper or acceptable alignment? is 1/16" + or- ok? 1/8"? 0"? it would seem to me that v-belts are more prone to jumping their groves than serpentine and / or wearing; so i'm sure it makes a difference.

any insight will be appreciated.

Post V Belt Alignment

Mike,
I'm surprised no one has replied to your thread.
I wouldn't go hog wild on this issue. Acceptable tolerance is about +1/16" You may need to fabricate a spacer.
Use a straight edge or if you have a good eye, do your best to line up all your pulleys. That should be all that's needed.
Good luck
