Default Starter knocking

Finishing up a tko500 from auto swap. When I try to start the car, there is a loud clicking/knocking sound from the starter. The battery has enough juice, as it was charged for almost 24 hrs and had a 50amp starting current running though it from the charger. Is the starter installed incorrectly? What could be causing the sound? Thanks.

Trying to help here but clicking and knocking are quite different symptoms. Does the engine turn at all or is it just noise? Clicking could be solenoid or bad electrical connection and knocking could be the starter drive jumping over teeth on flywheel (mis-adjusted starter) or loose starter bolts or incompatible starter for flywheel.

The engine does not turn over at all. I bought a starter for a manual car. The bolts are not loose and the electrical connections are correct. The flywheel is what would be found in a stock 4 speed car..

153 tooth flywheel is 12-3/4" dia and 168 tooth flywheel is 14" dia. An offset starter (mounting bolts) require a 168 tooth, and usually straight across mounting bolts use the 153 tooth flywheel. If this much is correct, try manually engaging the starter drive into the teeth of the flywheel and check that a paper clip wire will fit between drive and teeth. Also, if you connected the wire from ignition switch to the wrong post on the solenoid, this could be your problem. RE-verify you have the starter wires connected properly. You can also test the starter off the car by grounding it and jumping hot from heavy center post over to solenoid post, it should kick out the drive and spin the starter motor.

The reason I suggest checking the wires again is I switched to a mini-starter and mis-wired mine somehow and it would click and chatter in a very weird manner. I had the wires wrong on the solenoid as I recall.
