Need Help: Water Pump Removed - Heating Issue?

[camaro1969]

Background: 1969 Camaro, running a 350 sbc, aluminum radiator with electric fan (sucking air from grill inwards), 180 degree thermostat. While driving, I tend to start overheating quite quickly. Within 5 minutes of my drive, i reach 180 degrees, within 20 minutes i am about 200, and if I am idling in traffic at 200, I will reach about 220-225 within 4-5 minutes.

To find the bottom of my over heating problem, I pulled my water pump to see whether it could be a counterclockwise rotation on a v-belt system.

Are you able to tell by the picture whether the water pump i have is the correct water pump for my application? I run the belt on the grove side of the pulley and the pump pulley rotates clockwise (looking from in front of the car).

That being said, the water pump is a generic china brand, Dynapak np1063, I couldn't find more details, other than there is a "B" casted in the inside of the water pump housing. *see image* Can you recommend a good water pump replacement, american made?

Thanks
