question about waterpumps

[BeatersRus]

hey fellas,im working on an old 72 400 steel crank motor,and need to replace the waterpump housing and the pump.
while perusing various sites,i noticed that there was a long snout and a short snout? option ?? but no one seems to clarify that.
mine seems to measure out at 3 inches?

from these pics and measurements can you advise what i should get?
id like alum if possible.
motor is in front of a 4 speed,so i was also looking at the higher flow pumps?
thanks for any advice you can give.

I thought long and short was only small blocks, but i could be wrong. All the big blocks i would think are rather short snouted.

Where did you get that information? I never heard of it.

Pumps are the same. Sounds like you are looking at Chevrolet pumps. Water Pump & Housing Packages

All B & RB pumps are the same size. They would use a spacer to bring fan closer to the radiator

The cast iron small block is different than the aluminum one.

Get a FlowKooler water pump.

Why do you need to replace the housing ?
