We reviewed a few threads that went into this in great detail on pump/pulley/bracket combos and we were glad that we weren't the only folks having trouble figuring out the combos.
I think we have the bracket puzzle almost figured out. We decided to stay with the Saginaw P/S pump since most agree that it is the best performing unit but needed to figure out which brackets to use with the 69 cast iron water pump on the 340.
Wait,... there are two styles of Saginaw pumps?? Surely you can't be serious... I am serious, and don't call me Shirley. Well we now have two Saginaw pumps to choose from. One is referred to as the oval neck unit and as I understand it was used from 69-72 and the other is referred to as the box style unit and t was used from 69 - 74.
Does anyone know if both units perform equally?
If one unit is better than the other which one is it?
