Exclamation Water pump supposed to be reverse rotation...Why is it blowing coolant out the spout?

I'm trying to see if the water pump is the source of my cooling problem so after I replaced the crank pulley with the standard diameter and start the engine with the rad. cap off. I let it run a few minutes and then it starts to blow the coolant out onto the ground. Does this mean that I have the wrong water pump. It's supposed to be a reverrse rotation Edelbrock. But if it's blowing out does that mean it's a standard rotation??

It blows it out because the radiator was full when you started it, and as it heats up, it expands. Once the t-stat opens, it should just flow without blowing out.

Take care
