Interesting link. I think the theory is right, but certain things he explains I might debate. His method is mainly for bikes. Air cooled bikes. And they are very unique to properly break in. (I used to help my biker buddies at the track and learned a lot..lol) Technologically, most bike shops have modern equipment and the hi-tech machiing gets done. In automotive, I would venture top say that at least 50% of the honing done is too rough for the Moly irngs the guys tout so much. At least 50%. In a properly honed block, the cross hatch is barely visible, and it shines like it's polished. If you have honing marks you can feel with your finger nail, it's too rough. Also, you hear him mention using 4th gear. Bike engine dynos have to use the transmission too. Automotive does not. He also does not mention valve springs... Because a bike uses an over-head cam setup where there are no lifters. So whiel the idea of using pressure to seat the rings is right, his explanation and execution would lead to an eaten cam with any build having a cam over 230°@.050. I built a run in stand to do my initial firing now. It covers me by ensuring it isnt turned over 100 times trying to get oil pressure or the carb full of fuel, or figuring out hy there is no spark. It ensures I see any leaks or issues with my work before the customer has it in his car. It makes any repair or re-torquing, and valve spring work a breeze. And, it allows me to drop the oil and filter and check for issues. I cannot load the engine tho. The loading is what makes ring seal, and that takes a litle longer in an engine where it's turning 3500rpm instead of 6500 like a bike.
