I think as far as break in goes, it should be alright. The 500 break in rule ie: keep her at 55 etc. was something that was more of an observance on earlier days of engine/bearings/rings. The metals and alloys that they use to make those parts today are vastly improved so that the rings seat quickly. Today, break in on an engine can be as low as 200 miles. I may be wrong on saying all this. But this is what I was told by a respectable source a few years back. It seems to make sense what he said too.
