Yes...

The 351C 4V was designed from its inception to be a race engine. It was designed by Ford to make about 520 BHP at 7000 RPM with 11.0:1 compression ratio. Therefore making 500 BHP with a 351C is relatively easy, you don't have to purchase aftermarket cranks or heads to do it, it can be accomplished with the factory castings.

Enthusiasts have been building 500 BHP Clevelands since the 1970s, with the flat tappet camshaft lobe profiles available today it is possible to make 500 BHP at lower engine speeds (6000 RPM) than what we did in earlier decades.

You are correct that the short block needs to be blue printed to survive at high rpm, the valve train needs upgrading to run at 7000 rpm, and the heads need mild porting to make 500 BHP.
