A buddy's Monte with a new to him engine. The engine came from another close friend who had it in a drag car, and never heard the noise.
The ticking noise is what we're concerned about.
355 SBC, Hydraulic roller camshaft, alum heads and roller rockers.
The noise (with a mechanics stethoscope) is loudest directly under the carb, or on the trans bell housing. On the bell housing it sounds like you're hitting it with a hammer. There is no noise on either valve cover or head at any place.
The only places you can hear it are on the intake, the rear-ish of the block near the oil pan rail, and the bell housing.
We've checked and re-checked valve lash, pulled lifters and checked them. Everything there seems good.

Could be a bent rod.

Pull the bolts from the flex plate to the converter, then run it. See if it still makes it.

Meant to put in the original post, the converter is unbolted in this video

To update this, the noise turned out to be a bad valve. It was pulling a dish in the head of it, and was so tall the valvespring was letting it bounce on the seat.
