If your bearings are poured and fitted correctly then the run in period will have no effect on them.My only break in advice is change the oil frequently,within the first two hours to remove assembly debris,then four hours,then 100 miles then 500 miles for metal slough off from rings.

Dirt and debris introduced during assembly occurs no matter how clean you work.

Drive the car as you would normally.Almost all the failures of new engines Ive seen had nothing to do with how it was broke in,if its assembled correctly it will last.
