Waterpumps ,are they all the same ?

[Dakar Timm]

Our '66 Coronet 440 has the Polyhead 318 . Does this motor use the same waterpump as the "LA " 318 ?
If not is there a recommended supplier ?
Thanks for the help.

The inlet changed sides in 1970 I believe.

He's talking small block guys....I thought the poly water pump was a different animal than the LA, but I do not know...
I looked at rockauto....they are showing the same pump for many small blocks, poly and LA alike

Yes, the LA water pump is the same as the 1962 to 1966 poly water pump.
