Same fan that was on it before swapping the houseing and pump. Works fine.
They do go bad, expecially if there stored flat and put back on the car.
It's what keeps the engine cool(fan clutch) during stop and go. You should be able to hear the fan when it's working during hi temps.
I've seen em go bad with more than one car over the years.

Ok, so you changed the water pump, water pump housing, and the CAM...and you think the overheating is from the water pump?
I'd look at the cam swap before the water pump. with a cam change, your carb will need re-tuned, and your timing will need re-tuned. you could be lean, your timing could be way off...and that could be a HUGE reason for running hot.
I'd suspect that before the water pump.

Lunati 513/533 Initial is happest at 20 degree's yes new valley pan i never reuse a gasket. I think the problem is the pump. easy change to find out.
ALSO! Before bolting the new pump on, determine the impeller-to-housing clearance. There have been reports of interference and/or excessive clearance with some combinations.
I would think the most effective is for the impeller to be as close as possible to the housing, w/o interference.
As stated by another poster, the design of the 440source impeller does not look like it would flow well.
Report back with your results!

Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.
