If you turn the engine over by hand, do you feel compression? Does it make the normal dunk-a-dunk sound when cranking? Watch the valve train as you turn it over and make sure the valves are moving as they should. Check valve clearance. Make sure your plug wire is all the way on.
Depending on where the cams stopped when that gear lost torque, the valves could have hit the piston. If one is bent, you’ll probably lose compression and the clearance value will probably be way too big.
