This past Sunday an idiot who looks just like me was driving my '68 Buick and overrevved the engine causing a collision between some intake valves and some pistons. Odometer reads 79,500 miles. Upon disassembly I discover a perfect engine other than the aforementioned valve and piston issues which were right foot issues that I intend to address later and the mystery, totally destroyed cam bearings. I had difficulty getting the cam out, they looked like they had been run w/o oil for quite some time. But, the rod and main bearings looked excellent, hardly any wear indicated at all, the crankshaft is perfect, doesn't even need polishing. I hardly noticed any cylinder wear either. I was thinking with the cam bearings in their condition, that I would find other components with some damaged as well. Unless I have a blockage of oil flow between the crank galleries and cam galleries, I know of nothing else that makes sense. The engine is a 430. Any ideas?
