This guy knows what he is doing. I ran up on this video after I had added oil valleys with a file on the thrust bearing in mine. It will let the crank turn up with less friction. That engine I built is currently in a dirt track car I sold and nobody can figure out why they can't catch the car. 😂 I'm figuring REALLY that the extra oil and a high pressure oil pump is letting that crank turn more than the average RPM. I had it at 7,300 passing the flag stand mid straight away before I sold it. Plastic gage all crank journals at .003 of clearance. Loose engine. Could turn the crank with 1 finger after all bolts were torqued.
The way I do it is foolproof. I put a big C clamp on the front weight of the crank and front of block with the rear cap snugged down like you said loose but tight. The clamp pulls the crank all the way forward. Then I tap the rear cap backwards with a pin and a few hammer taps and then torque it. That way I know the thrust is aligned perfectly
