holden, red-blue-black water pumps

[fccool59]

I still need a water pump, pushrods and a new flex plate to complete my motor, due to a second pulley in front of the water pump/alt pulley I want a short pump, also I only have electric fans, no engine fan.
I have noticed the later model blue and black motors have a much dearer pump, does this pump work better than a red pump?, does it last longer? does it fit the red block ok?

I think you will find the dearer pump will be the heavy duty bearing one for the extra weight hanging of the front of the pump. viscous hub (fan),air cond. etc.
