440 source stroker crank pulley alignment issues.

I installed the timing chain and lower gear and cover installed. The crank damper and when I went to line up the crank pulley with the water pump pulley it was set in a 16th to an eighth of an inch in farther than the stock. 440 crank. My question is would there be any issue to make a spacer to slide on the crank that would go up against the lower timing gear and then put my balancer on and makeup the distance that is needed to line the pulleys up. Here is a picture of the crank. Any ideas would be appreciated.
