Awwww help im getting mad

[74chevy3/4]

ok as my title says im getting mad and thats when you start missing things ...

so here it is about 2 weeks ago i replaced all my plugs, wires, cap, and roter.... ran better then ever soo soo happy. then on New Years Eve a lady backed into my front passenger side in a parking lot =*( "yes i cried"

No major damage slow speed fender bender. damaged front fender bumper brush guard marker lights and bezel. Engine compartment appears unaffected.

Now runs very bad. Misses at idle gets worse with throttle often stalls like someone messed with plug wires (didn't happen). I have checked all plugs wires cap rotter. Got it all and making good connection.

what should i check look at anything. I don't think it has to do anything with the crash but why did it run great then not?

I need to get this running well again its my daily driver please and thank you
