Can anyone help me find the right water pump pulley.
My 1969 440 swap appears to be originally an AC setup. The crank pulley has four grooves and the alternator has two grooves. There is no AC compressor, just an idler pulley. The water pump has a single groove pulley that is very shallow.
There is no belt on the rear-most groove of the crank pulley and alt pulley. The next groove forward runs a belt from the crank pulley to alt pulley. The next groove forward runs a belt from crank pulley to power steering pump. The front-most groove runs a belt around crank, water pump, and idler pulley. I want to eliminate the idler pulley and run a larger belt around crank/water pump/power steering pump.
I know I have to change the water pump pulley to one that has a groove one notch back from the one I have now. I don't care if it is a single or double groove pulley as long as the groove lines up with the crank and power steering pump pulleys. The groove center on my current water pump pulley is 7/8" from the front edge. I need the new groove to be about 1-9/16" from the front edge.
I've looked at other pulleys online but the deeper ones are WAY deeper and some folks even talk about them hitting the water pump bolts. I don't need anything that deep, just the equivalent of one groove to the next.
Here is my current setup
