Belt size for LT4 blower 2.5 pulley

Hi guys, Im currently pulling down my LT4 blower from a 2.75 to a 2.50

I know that the 2.5 pulley is the stock size however considering that in order for the LT4 blower to be bolted on the LT1, spacers are requiered. My brain says that the stock ZL1 belt wouldnt fit, correct? Since the blower will be sitting slightly higher than where it would sit on a LT4 engine....

I currently have a 2.31 pulley and belt (which I never used) but I was told that the belt might fit on the 2.5 pulley... thoughts??

P.S lower pulley is the stock ZL1. So I would now be at 2.5 griptec high and stock low.

Thanks in advance for any help... I would like a green belt also.
