How common is ?
The 300 at eating main bearing and rods prepaturely say under 200k.
I helped a buddy take out a EFI 300 with 168K and ALL of the bearings where showing copper, BUT the engine was clean-no sludge.
Was that just CHEAP oil every 5K or is the 300 a bearing eater?

Was the engine knocking? I have had many engines down with less than 10K and found dase metal and not knocking. Put a few back to together and they ran for years and we (at the time) teens were hard on a car!
To see base metal at 100K+ would not supprise me at all in any engine!

No the 300 is not a bearing eater. It actually has more support on the crankshaft than most v8's. Im almost done with my 300 rebuild and when I pulled it all most all my bearing where showing copper. I didn't knock though. Held decent oil pressure 45 cold, 20 hot. The biggest thing is changing oil regularly. I do it 3k or every 3 monthes. It had over 314,000 miles at the time when I pulled it.
