I fixed mine a few weeks ago, just reporting now...so is it still only a buck? My 67 400 (with a 70 timing cover) always got hot at idle, running it would stay around 190, but at a long light maybe 210, and at worst 220. I pulled my pump and found a stamped one. I adjusted the backing plate and put it back on while i looked for a cast impellar (and it was scheduled for it's annual inspection the next day). I saw improvement with the performance of the stamped one, but still not really acceptable results at long idle.
I put the cast one from NAPA on two weeks ago and got 2 miles before the power steering pump (It was on it's last leg since spring) decided to squeal like a school girl. Now that I got the new pump on, I idled it in a hot garage (90 degrees) for a long time and it never went over 180. In the garage, it was typical to see 200+ quick)I'll run it good and long on the interstate this weekend, but I can already see better results.
George, the results are even worth the 2 dollars, and I was surprised at the improvement with the stamped unit. My tolerance on the cast unit is tight, I worked it down to touching each of the impellers, then put the gasket in between and bolted it up.
