The new high performance water pump we got has a different bolt pattern than the old, so the 5" steel pulley doesn't fit, and I had to order the one designed for the pump fro BRD Racing:
Their water pump pulley come in either 6" or 7", and the idea behind a bigger pulley is that " The 2TC and 3TC Water Pumps Are Notorious For Cavitating When RPM's Get high Causing coolant flow to suffer. This Pulley Combined with our High Performance Water Pump Will Keep Your Street or Race Engine Cooler, Even in the Most Demanding Situations!".
They recommended mating it with their 3.5" crankshaft pulley, which I ordered as well.
I am a little concerned as just how much slower that's going to make the pump RPM, and the Alternator as well.... But I talked to the experts at BRD, and they say that's what we want....
The engine is basically finished now, and we are just waiting for the clutch to arrive on Tuesday to put it back in the car.
