The pilot reported that the airplane, which was used for sky diving operations, was climbing through 7,000 feet mean sea level (msl) when he heard an explosion followed by a metal grinding noise coming from the engine section of the airplane. He felt the airplane vibrate, and smoke began to fill the cabin. He reported that the engine was not producing any power so he shut the fuel off and performed procedures to rid the cabin of smoke.
