I doubt the timing light was bad because they don't usually advance. You could have a faulty module that is over advancing, if your dizzy is locked your springs are not losing control.
I guess I would change the module out, if that does not fix it get another dizzy and try it.
50* of timing will kill just about any SBC making decent power as it will burn pistons and kill ring lands.
Can a bad module affect timing? I'm still not sure if this supposed 50* total timing was actually there or not, since retarding the timing resulted in less power. Also, there was no audible spark knock with the hood up and standing right by the motor during the several pulls we did. Lastly, the motor still runs fine as far as I can tell, so I don't think anything was damaged as a result. Having said that, the motor does have forged pistons.
