Sounds like something is turning the input shaft with the engine running. If you have the space, might try starting it with the transmission in gear and the clutch disengaged (this is not a safe test!!!). If the input shaft is hanging up somewhere it might make the car start to move when the starter turns over. I would think that the input shaft is to tight or hung up somewhere, like the pilot bearing or the back of the crank. The input shafts are too long and extend past the pilot bearing, it may be hitting the back of the crank hard enough to make it turn. They need at least 1/4 inch cut off if it is hitting. Cornhuskers says 1/4 to 3/8 and then chamfer the cut end so it fits into the pilot bearing easily. Are you using a roller bearing or bushing pilot bearing?
