Looks like the Clevites are going back in. Cost and availability are factors here. Im running the Performance bearing, so its not the standard at least, and the rest looked awesome, so it was that one only. A new theory, if anyone remembers, I had a crap injector spraying to much fuel on fire up. It was so shot that the engine would not idle less than a 13.5afr. So during cruise at 15.5 and on the dyno, just how lean were the other cylinders, and if number 2 was squirting just alittle less, is possible that detonation took out that rod bearing, and it just took the rest of the program and 4k miles for to detoriate.
Im looking at a 2qt Accusump at this point as a preoiler. My thought is to have a programmable output be on for like 4-5 seconds with key on to prepressure the motor, then have an "or" condition that opens the valve at more than say 50% throttle. This will keep oil pressure if it ever drops and maintain more pressure in the tube than idle will pressure up. Kind of a win/win all around.
