The 528 is a nice manner streetable cam that isn't a real radical cam. Doesn't have as much in it as the 509 hydraulic though as it is really a lesser cam after you take teh lash off you end up with like 500 lift. The .557 will give you alot more but will not be quite as street friendly.
unless you set the lash at .022-.026

Even at .022 and .026 it will net less than the 509. Not mush but less. It will be 506/522. Never the less the seasonal running of each in the same engine, same car netted up to 2 tenths average less ET with the .528 but better mannered.  PS: that is even trying various lash adjustments. Do what you want. For the street I would chose a 509. For more strip than street the .557. 
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

509 needs more stall than I wanted to run and doesn't work as well down low and pulls terrible vacuum. And this cam was already in the car.

Basically what I was saying. IMO you will very likely be happier then with the .528. It really isn't that bad a cam, just depends on what you are looking for.

I would consider the 528 and 557 to both be good street/strip cams. With the 528 being much more towards street and the 557 leaning much more towards strip. If you have an iron headed big block, the 528 is good if you've got 8-9:1 compression, stock or mild stall and mild gears, or exhaust manifolds, etc. The 557 is more suited to 10+:1 compression, headers, high stall converter and steep rear gears.

The .528 works real good if you are running exh manifolds. But as was said it sounds very mild in a bigblock and with headers the .557 will make more power in a mild street/strip combo. I run the .557 in my 63 and we have one in my boys Dart. Myself I think they are a nice street cam as the idle really is not that radical after it warms up. It is very easy to live with running the 9.5 Dynamic converter my son and I use. I would consider running much more cam in my street car as I guess I am so used to the .557. But it makes great power in our cars. My son runs 3.91's in his Dart and I run 4.30's with a taller tire then him. Both cars have great low end and pull nice up top for a mild street combo. If you want a mild idle with good power use the .528 but if you want alot of power and a choppy idle go with the .557 as long as your combo will support it. Ron
Oh I forgot to tell you I use 906 heads and run 10.0 comp and it runs fine on 92 pump.
