340 tunnel ram issue

i dont hear any weird pings or knocks / noises. but i dunno? i am going nuts over it about to either pull intake and replace it and carb and do away with tunnel ram or i am about to sell car and be done messing with it. i just dont know why it wont even drive down street yanno? and that is what makes me so annoyed. i am going to check plugs, wires and also for vac leaks yet again tomorrow and also get carb info and spray them with cleaner.
