did you just rebuild the bottom end with out a machine shop? if so you just encountered the 200 mile rebuild.
bearings have no break in time what so ever. those tolerances are set when you torque the blots down. and being the cam uses roller lifter theres also no break in time for that any more.
back in the day with flat bottom lifters you had to break in the cam and lifters, let it run for 30 minutes at 3000 rpm's give or take.
but those days are over, once a newer engine is built its go or blow. only thing that needs re seating is the rings and well the harder you drive it the better they seat.
