Bend rod?
Started my new 427 build up to make sure it fired and no leaks before going to get tuned. It ran for approximately 3 minutes before noticing the passenger side coils weren't plugged in. Plugged it in and it wouldn't turn over. Fearing the worst that fuel was dumping into those cylinders and maybe hydrolocked the motor.
I pulled the plugs and was able to turn the engine over by hand. Started it again to see if it would fire and it did, but didn't sound pretty.
what are the chances I may have bent a rod or valves?

I seriously don't think you damaged anything. It would take substantially more fuel than what is provided by the injectors in a cycle to hydro-lock the engine. It is a 60+ cc chamber so that is more than a shot glass of fluid in size.
My guess is that you had un-burnt fuel igniting in the exhaust. I cant think of a reason why it wouldn't start after you connected the right bank wires unless the PCM need a few ignition cycles to relearn that bank of coils and get everything else in time with them.

You did not realize something was wrong when it was only on 4 cylinders for 3 minutes I am not trying to be rude but you may want to have someone with more automotive knowledge look things over

Even a severely out of time engine that needs jets adjusting will not run like a engine on half of its cylinders. Lack of power and hesitation is completely different than dead cylinders.

Sorry for the delayed update, had some house projects that took priority. So, after taking a closer look I pulled the plugs and turned the motor by hand. Turned over fine. I sprayed fogging oil into the plug holes and spun the motor over. Had the computer tuned with a base tune so I could properly break the motor and clutch in before getting a dyno tune. The car started right up and all is good. Purrs like a kitten. Thanks to those with the positive and informative posts!
