So I've got the engine mostly together on my 89 Comanche. Engine setup is 92 HO short block, the 93 HO head (7120), AW4, flexplate, and the starter are all from the same 93 XJ donor.
When I crank it over, it makes this scraping sound. It doesn't make it if it's running, only with the starter engaged. I've tried another starter I had lying around, same issue. Flexplate isn't cracked, the bolts are tight, and the teeth are fine. No rub marks anywhere on the flexplate, bellhousing, or starter. Any ideas?
