Way too small for a 527.....way too small for a 482.....way too small for a 445... LOL
For a 527ci engine, if you want a nice cruiser that peaks at about 5500, you'll need about 250-255 degrees of duration at .050". That would be a hydraulic roller.
If you wanted a solid roller, you would need to add about 10 degrees to that to account for the lash take-up on a solid cam.
