im sure they do now. times change and they decide we can do things differently. i have a friend that has been wrenching since long before i was born. having built several engines himself he doesn't believe in a break in period. he runs them wide open from the moment hes got it running. my point is, we all learned that you should break an engine in. but that doesn't mean it has to be done that way.
