Ok thanks bro

You probably need to install new motor mounts. Likely the stock ones are super worn out and allowing the engine to move around a bunch and let the power steering pulley hit the frame.

No power at low rpms and smoke could be a compression issue. That’s where I would start first. If your compression is nominal on all cylinders meaning they’re all about the same psi, then valves or valve stems. Have you done a walnut blast? Timing corrections are normal at low rpm as their is a greater load on the engine at low rpms. a data log would be useful for us.
