    I dunno, but if it were mine; I would look for a longer blower snout (I know they made long and short ones) because all three of your v belts are in correct alignment and the inside most one is right on the balancer.

    I tend to agree. I don't think that even if he gets the blower and crank pulley to align that he will be able to get the v belts to clear. I think he has a street "single" belt setup there, not the 3 v belt marine setup. I still think he is going to need a different lower v belt pulley though, because the 2 blower pulleys should still line up, even if the v belts can't clear the blower belt if the blower was installed.

    The blower snout is definitely short. If gets his hands on a longer one, the lower blower pulley may need a spacer behind it, or the correct deeper crank pulley used with the longer blower snout.




    This snout measures about 10.5 inches from mount flange on the blower case to the end of the casting.
