again, good informative vid.if the rod length is a quarter mil out, and the crank not true/concentric, you can see why production tolerances are so wide.add in a cylinder and head that aren't accurate and you can see why the manafacturers have to assume the worst possible parts matching in production, which is why blueprinting is good for reliability and you will see small (maybe 1 or 2hp tops) power gains; the further away from true your engine was, the better it will feel after blueprinting.

unbelievable attention to detail, if you want an engine built properly, old school, this is the man.
