LA 360 - 0.030" Undersize Main Bearing Clearance Questions

Ok, guys. This is a little know fact. The smaller the crank journal is the slower the bearing speed is. This is a win win. As far as his clearance is at .0018 and .0019 that’s .0001 ten thou of an inch. Just send it and it will be happy. The OP is making a mountain out of a mole hill. I’ve had factory big block cranks turned .060 many times years ago. They turned 7000 no problem. Kim
