After building an oil pickup, modified oil pan, and most of the oiling mods, it makes me just want to go to a dry sump system if I wanted to run over 6500.
And it still doesn't fix the oil timing issue. That's what kills bearings at high RPM. At 1965 designed SBC style oiling system will oil the rods efficiently to 10k yet, depending on several other parameters 8000 is about max on a Chrysler without correcting oil timing. And that year SBC oiled the lifters first.
It was a piss poor bean counting decision to time the oil feed the way it was done. You could forgive the thinking somewhat, if you consider the people at that time thought 7000 was in the stratosphere.
