Pat, you are the experienced machinist that I outlined in the first part of my reply. Not everyone has the experience or the tools or the controlled environment like you have to work in. Some of us have to work on dirt floor garages in the cold, where, even if the mic was just zeroed, it ain't gonna be accurate for very long, not to within 2 tenths anyway, even if the average guy knew how to measure and read 2 tenths. He'll be lucky if he's within 6 or 8 tenths and in the end, it won't matter anyway because he's probably not trying to build a precision motor like you would build one and I hope he has the common sense to realize that.

Just trying to be real here. You can put a motor together using plastigage and it will pull your beater down the road and hold oil pressure if you used the plastigage correctly. If you want or need a precision motor to compete in some venue of racing or if you simply have the money to buy the best motor you can, then contact Pat and let him build it. End of story.
