Quote from post #5:"I know some say the depth is the issue on the 4.3 pulley but mine seems to be fitting the snout into the stock 8" harmonic balancer. The crank pulley snout seems to big"?
Quote from post #10:"You need to place that pulley onto the balancer and see if the part that fits into the balancer is tight or if it moves too much".
Did you do that? If the snout fits, then install it and see if the depth is right. If the snout don't fit, then it don't fit nothing to discuss.
Anything else? Diameter or belt width?
