Good luck!!!
If your cam bearings have failed, generally there is far more wrong with the engine than just that.
Likely it needs a total rebuild. On that engine you can't even begin to get near the bearings without taking over half the engine apart anyhow.
There really isn't anything wrong with the engine in general. It has 280k miiles on it and I'm using it to tow a 5k lb travel trailer. The oil pressure drops low at idle, and I'm pulling the engine any way to replace the crank and rod bearings and the oil pump. So I figured that as long as I had the engine out, I'd also replace the cam, lifters ,and cam bearings
