What to do with new motor?

I don't understand why you would want to do that. When I fired up my new motor with new cam I used 50/50 mix and I was done. I fired the motor and kept the RPM at 2200... temperature started going to 200 degrees and I shut off. Let it cool down and fired it back up until I got 20 minutes with motor ran at or over 2000RPM. Coolant in the water helps hold heat so the heat will make its way to the radiator. Use a big fan in front of your car if you have one while doing the cam break in.
