Is there an inspection cover on the bellhousing? Lots more leverage there prying on the teeth.
One MORE reason I hate those little SOB’s.I recently tore two 383's down that I had hopes of making run. They looked clean on the outside, air filters still on, etc. Found a large mouse nest down a cylinder on both engines. They had entered via exhaust pipe, and down by an open exhaust valve. Will require new pistons and boring the cylinder to get that mess cleaned up.
