The grinding you hear may be the starter drive itself not grabbing due to wear. They make a grinding sound because the starter drive is slipping inside. Sounds a bit like an old starter on my 58 Chevy with the 235. I would push the stomp button down and when the starter went to spinning it would make a horrid grinding sound. Had the starter rebuilt and a new starter drive installed and it worked well for many years.
