Another Cast Iron Pump
In conclusion. We believe if you want a 4.25" impeller
pump from NAPA you need to order part number 43100. You then need
to check the box for a little number of 130-1260. After that, I
would open the box and measure it to be sure it is really a 4.25 inch
impeller pump.Ken B.

Water Pump
The correct water pump has a cast iron 6 paddle blade of 4 1/4"
diameter part # 412265-D24.
It must have the D24 on it to be the correct one.

Ray Curtis no longer has a supplier and cannot get water pumps anymore.
The following is a picture of the CASPRO water pump.
Looks almost identical to the original style. Has 4.25 inch blade
that has a backing.
Available from AJ-USA for $90.Hope this is useful.

Another Cast Iron Pump
This is clearly not the pump suggested above. The impeller is
only 4 inches. This pump was on my 455 GMC and seemed to do well.
This is the pump used by Mondello on my new motor. I think it is the TRW FP1524HD pump.
This is the pump that Winterfeldt supplies. I believe it is
the TRW
pump also. You can see it is a 4" impeller with eight
paddles
but it has a backing plate similar to the cast iron impellers.Thanks
for the picture Manny.
The (less expensive ) water pumps use stamped metal paddles and have no backing plate. These do not provide the volume povided by the factory original parts. If your engine and radiator is in excellent condition many are getting by with these. Mondello, Winterfeldt, are not using these pumps.
This is the pump supplied by Cinnabar. Thanks for the picture Arch.
I know of one local GMCer that put this pump on, now his fan clutch comes on all the time on flat land.... He is going back to a pump with a backing plate. Gene
