I am looking for a good aluminum water pump and pulley set up for my 1970 455 Cutlass S. The car will have A/C looking for some info from anyone that has done this.


Thanks,
Mark

 

The aluminum pumps I have seen (FlowKooler) are made for the later '71 and up engines with the smaller inlet on the pump ('68-'70=2" water pump inlet and 1.75" radiator outlet; '71-up=1.75" water pump inlet and 1.5" radiator outlet). I guess you could swap out your radiator, or just have a shop swap the outlet hose fitting for a 1.5" one and then change your lower hose to a '71-'72 version.

I have no idea about aluminum pulleys.

 

Thanks for the info. I will be picking up a new aluminum radiator so I will get one that works for the pump.
