Seems the stuff out there does not do as good a job of cooling as the OEM cast iron pump does. I started a similar thread on that forum. So far, I found out that Mopar Performance makes an aluminum pump that is a similar design to the cast iron one. Looks like that might be the best bet...Thought I'd ask you guys as well... I've got a 67 300 'vert with the 440 High Po engine and it does not have A/C. She kinda runs hot in the summer when stuck at traffic lights, so if I decide to replace the pump with an aluminum one, it has to perform as well or BETTER than the OEM big block pump.

Even the Milodon pump looks very close to an oem pump. If you buy an edlebrock pump be sure to pick up a hi-flow t-stat to go with it.

Someone else can correct me here but I am pretty sure I have seen them with different number of blades on the pump itself? I may be wrong but they may be different flow pumps? Joe Sr.

Eddy pump is a more modern design (cast iron wheel with curved fins). It's also more expensive.

If not then get one. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I've been dealing with the car getting hot at traffic lights during the summer for 3 years now. Right now, I'm thinking of replacing the water pump for other reasons...trying to do my research before I do this.. IF I replace the water pump, I'd like to get an aluminum one to save some weight. There was a discussion on Al water pumps on another forum...seemed like most posters did not think the Al pumps (aftermarket) were as good as the stock cast iron pump. So my question is simple, despite all the words...IS there an Aluminum water pump out there that FUNCTIONS as well or better than the stock OEM cast iron pump....on Big Blocks.. That's it!!!
