Modern muscle cars are pretty easy to massage extra HP out of. A change to the fuel and timing curves can get you a lot. Beyond that you have to change heads, injectors,intake manifold. Any more than that camshaft and pistons are next and you have to pump the compression up tighter combustion chambers or turbo/supercharger.
You make your horse power with compression ratio, the tighter the better.
