Why so much inital timing???

All assuming it is a true 10.1 motor which I see no evidence of, he has no real idea for he didn't measure it himself. I bet its more like 9.5 or so, but only way to really know is by taking it apart and measuring everything.
The question was undoubtedly answered as to why he can crank up the intial so high...but yet you argue that.
You can all build how you like, or claim to at least, but don't for one minute assume you do it better than everyone else.
