      Break in oil question

      I am building a nice little 406 small block flat tappet motor for my car. What break in oil are you guys using in your new motors to break it in? How long are you leaving it in? What oil are you using in your motor?

      I have used the Driven break in oil on three engines so far and it seemed to work well. https://drivenracingoil.com/c-138919...mbly-oils.html
      Choose the correct weight for you and change it out after about 500 miles. I would then replace it with a high zinc content oil of your preference. Too many oil choices out there, but do your research and make sure it has a high zinc content.
