After spending my lunch hour at work today mounting my new high performance puller fan to the radiator I bring it home to put in the 'stang. Here is where the problem lies. On the I-6 the water pump hub juts out from the block 4 1/2" and then the belt pulley which is dished out slides over and past the hub so that the belt will line up. Does anyone know if there is a water pump that will bolt up with a shorter hub distance. I have already mounted the fan and am sure it can't be returned. (not that I want to, as it really moves some air.) I am wondering if later model 200 or 250 6cyl's have a shorter shaft length. I need to gain about 1" clearance. The depth of the 16" fan I have is 3.39" and puts out 2360cfm, there is anothe 16" fan with a 2.05" depth but it only puts out 1378 cfm, will this be my only option? Thank you for your help.
