FE Water Pump Pulley?

[talos]

My original cast iron water pump, has an aluminum pulley, with 1 1/2" center holes with 6 9/16" diameter(single grove). The pulley will not work with my Edlebrock aluminum water pump. It has 1 1/4" center holes. I only have three pulleys on this engine(water pump, balancer, & Alt). Any recommendations for a complete set of billet aluminum pulleys(single, serpentine)? I also have read diameter on the water pump pulley is crucial.

Thanks,
Tom

talos Tom March sells 2 different pulley setups. DON'T run the under drive setup. You want the 1-1 water pump to crankshaft. You can do what you want with the ALT. Go to CVF racing and they will have the setup of high flow for your motor. You can use either grooved belt or surp belt setup. Simple chart and part numbers for each pulley to match your motor. Also, pull the back cover and look to see if a disc is mounted to the fins on the impellor of the water pump. If not buy a kit to stop cavitation of the coolant. Good luck Ps the edel brock pump has a disc. I missed this, sorry. Rick
