Keep an eye on oil pressure and water temp and get a decent timing advance so it is not running too hot. Helps to have a buddy there for another set of eyes. Make sure to use oil with zinc additive. I used Joe Gibbs break in oil and a comp cams oil additive.

Thanks for the information. I just bought 5 gallons of the Lucas High Zinc Break in oil. I'll drain what I have in there now.
