Turn the headlights on and crank the motor. If you do not see the headlights dim then the starter is not even trying to spin the motor over.
On the other hand if when you go to crank the motor and all you hear is the sound of the drive smacking the flywheel then the motor itself is lockup and that could be for a few reasons.
By the way the Olds 403 is a great motor if you put different heads on it.
It’s got a real big bore, 4.315”.
