Want more power out of 427

Hey everybody I have a few questions in hoping you can help me with. A friend of mine currently has 427 bbc that ran 520hp on the dyno. Now after a few years he wants more power closer to 650hp. No nitrous. He is on a very strict budget. Now the motor has forged crank and forged domed pistons. Now I thought in my mind he could disassemble the motor have the pistons milled down to be flat tops giving it around 8.5:1. Put a weiand 177 blower ontop. Possible upgrade to a hydraulic roller.

Would this work? If not could I get input on what you guys would recommend? This is strictly a street motor in a 71 gmc half ton.

Thanks a bunch
