1968 Suburban Noise from TH350/350

I don't post very much, been a member since early 2000's. Get a lot of help off reading everyone's posts.

My daily driver started making a banging noise. Anybody have an idea as to what would make this noise? (in youtube link) I've checked flywheel, torque convertor bolts, starter. I got nothing.

Thanks for any help

Not sure what that might be. It almost sounds like a random engine miss.

Unbolt the converter and see if it still does it

Yup. I'd be looking for leaky plug wires.

Pre-assembled wires? Take a look under the hood at night
