I had a very similar combo with 9.5:1 CR, 452 stock heads, stock intake and 2500 stall convertor.

I used the .528 MP cam.

Very slight lope, great low end punch, and pulled well past 6k.

In a heavy street car with 3.23 gears the car would do 104 mph in the 1/4 mile.

Want a little more lope and have a bigger converter then the .557 might be your best bet.
