We are kidding ourselves to think this can be resolved by simply replacing the bearings. He is are not running rounds at the drag strip. This is going to entail a complete inspection, disassembly, clean up and rebuild. The top end is probably salvageable but the bottom end will definately require work, possibly even the piston bores. One small particle of metal or (?) can keep the pump bypass open BUT with the engine fully warmed up and at speed on Willows and at tun 3 the oil will be doing crazy things inside the pan especially if there is no scraper. Pete: If the plate with the scraper which bolts
to the bottom of the Aviaid Cobra pan was left out to allow for the girdle, I would encourage you to rethink that decision. The floor pan/scraper is much more crucial for Road Race/ Open Track application with 331 stroke than a girdle is, unless you're running 12.5 Compression or Nitrous.
It is easy for all of us to "Armchair Quarterback" the situation, we all have an opinion. This was a bearing failure that cause the annihilation of the bottom end. Unfortunate. Not the kind of Gold Panning you want to do...........
