This certainly has been a concern to me. I posted a question about
water pump options for my HiPo 289 rebuild a while back. The original
pump had a curved bladed cast iron impeller, but was in unknown
condition. I located a Ford replacement pump, but it had an impeller
made of stamped sheet steel. I checked into aftermarket water pumps
and discovered that they also had stamped impellers.
What I ended up doing was having my old water pump rebuilt. I don't
know if this pump will have less cavitation than any of the other pumps
I could have installed, but I figure it can't be any worse.
