I'm in pretty much the same camp as Stingray70 and kawagumby. New engines these days are made to tolerances not possible when our cars were made and out of materials not available using techniques they couldn't dream of. An engine rebuilt by the best workshop today will only be to about the standard Ford attained in the day. I don't think it is reasonable to compare a new engine with a Model A engine, new or rebuilt.
The engineers of the day knew what they were on about and they were quite strong in their recommendations that an engine be run in properly. That'll do me when dealing with one of their engines.
