I've done a comparison with ported and filled versions of both but, not either being "out of the box".

On that particular EMC engine the P-51's had more horsepower and the SCJ's had more torque but, the averages were the same from 2,500 to 6,500 RPM.
Now, in an engine with a larger camshaft than what is needed for a competitive EMC engine, I can see the P-51's running away and hiding.
