If you're keeping it or selling it, you'll still need to put a working engine in it, so there's that.

When the 440 stroker in my car died, the rebuild quotes here in LA were so high that I ended up buying a 462 from Kaufmann. They'll break it in on the dyno, tune it, then crate it up and ship it to you ready to go.

Good luck!

Yes, a lot will depend on costs involved here. If it's up there quite a bit, I may end up going a route like that.

As the rod journal ground away at the bearing (the growling sound) the clearance was partially restored and oil pressure returned (albeit lower). This quieted the valve train some. You probably wiped out the main bearings too but only an inspection will tell. An event like that usually starts with a momentary drop of oil pressure or a fluctuating oil pressure gauge needle that wiggles a bit at first and then eventually drops.

I keep a pretty good eye on my oil pressure. It's never fluctuated that I could tell. However one thing that I did notice recently, probably within the last month or so was that the pressure was ever so slightly slower to come up after engine start and during cruise, it was actually running about 5psi higher than typical. I attribute that probably to all the sludge that was building up in the oil and it's increased viscosity.
