Please Help!!! Any input is apretiated I am building a 69 camaro ls1/t56 , all aluminum f body block, texas speed flat tops and torquer 4 cam, car runs perfect the only problem it has is a small popping noise from the passenger side exhaust (true duals) i will try to attach a video, it only does it while idling, i have swapped coils/wires/plugs with no change, even pulled wires while it was running with no change, it has 90 psi fuel pressure which i will drop the tank and figure out tomorrow (has a vette fpr) and i know that is a problem but not sure if it would cause this. I am open to any advice i'm thinking maybe a bad injector or maybe the excessive fuel pressure?

I have checked for leaks, i even ran it open header and it still does it, it almost sounds like a "knock" in the video but in person it is a "poping" sound coming out of the pipe, i was thinking maybe unbernt fuel in the exhaust igniting?
