68 Dart starter issues - any ideas

Turning the motor over manually from the harmonic balancer bolt. The torque converter spins with it nothing weird there. If I take the bolts out of the flex plate how freely should the converter spin? Thanks for all the responses. Great site.

It will feel like it has some resistance just from the weight of it, it should spin fairly freely though.

Like mentioned, did you use the correct bolts?

Does the engine turn over like it should via the starter, just making noise?

Do you have a dust shield/inspection cover on the trans?

Sometimes they get bent and the bolts will chatter on it.
