I am building a 1971 Olds 442 W30 clone and need some help on water pump selection as well as pulleys. The car does not have A/C nor do I plan to add it.

I bought new pulleys for it but not sure they are correct. Here's what I have: 2 groove crank pulley "KJ", 2 groove water pump pulley "KM", and 1 groove P/S pulley "KC". I now have to select a water pump and I was leaning towards the high-flow FlowKooler model #1775 that's the long 6" shaft model. I will be using an aftermarket radiator too with possibly electric fans vice the clutch fan OEM system.

Will these components I mentioned work together and provide me the high flow capacity I am shooting for? If not, what do I need to change or buy?

Thanks.

 

The FlowKooler #1775 is for AC cars. You will want #1776 which is shorter for non-AC cars. Here is a pic of the '71 assembly manual which shows the pulleys you will need.

Rodney......got it. Thanks for the help.

 

Note that the KM pulley is to be used with a 5.5" tall water pump. KN pulley is to be used with a 5" tall water pump. Also test fit everything before final install.
