When to freshen engine

I guess that I need to ad that with it having 380 runs on it and you not knowing the warm up practice was done properly I would do it now...

Bill Miller will tell you that with the proper oil warm up you can run them in a street motor as long as you want.. I have one with over 30k miles on it..

But I do know that it is plugged in with a block heater and I let the car get up to temp before taking it out and stretching it's legs.
