I have files containing compiled Python bytecode. I want to run them through my executable program without the massive overload of the Python interpreter.
Any ideas?
You mention the massive overhead of the interpreter: do you have any evidence that the compilation step is massive overhead?  You might be misunderstanding what is in a .pyc file.  Python bytecode is not machine code, it is very high-level bytecodes that are executed by the Python interpreter.
In any case, no, there is not a build of Python that can run .pyc files and not .py files.
Is there a light version of Python that only runs .pyc files?
