If I recall, since the OE type alternator bracket originally used the pump casting to achieve its spacing, I had to use several alternator tube spacers to space the bracket back out from the now, shallower, depth of the electric water pump. With the motor of the electric water pump being so much fatter, and sticking out further than the OE pump, the belt running right from the crank pulley to the alt actually hit the motor housing. I had to lower the alt, but it wasn't enough with the bolt in the upper head bolt. So i moved it to the lower position, clocked it some, and put on a much shorter belt. I left the OEM crank pulley on it at this point, which was a mistake. I threw belts constantly, but i shift at 7100. I then tried the moroso pulley, and it took care of the belt throwing issue. only point to make about the moroso pulley is that it has the single off-center bolt location like an early chrysler balancer, so most will have to run one less bolt.
