Is this the sound of rod knock and eng failure?

(I just got back to nm and he lives in reno nv so there is no way for me to get up there and take a look at the car.)
Yup, pretty much without a doubt a Rod Bearing Failure

I'm really sorry man, I highly recommend draining the oil to diagnose rather than running the engine any more. Just to prevent any flake from circulating around the engine any more than needed.

It's funny, a stall out was the last "abuse" event on my car before it spun a bearing. I let my uncle drive my car for a cruise. He's battling prostate cancer and he was telling me about his treatment so he wasn't paying attention. We pulled up to a stopsign after cruising in 5th and he stalled it out reaaaaallly bad. I was trying to tell him "Push in the clutch push in the clutch" but his mind was elsehwere, I had to pull the shifter hard to pull it out of gear but it was too late.

The engine made horrible noises while it stalled in top gear but it started right up and drove fine for a week. I don't know if it was that stall that caused the failure or if the engine builder who put in my last engine re-used the oil cooler from my last spun bearing or if I just abused the car to the point of failure on my own and I'll never know.

I just want to hear more from folks who've had a rod bearing failure and rebuilt to learn how long their rebuilds have lasted without problems after the fact because one of the builders I've talked to for fixing my current bearing issue said the chances of failure after spinning one rod bearing are extremely high unless you replace every single oil passage on the car, replace the entire longblock and even the turbo.
