Can this break in be done after the motor is pre-tested and back in the car?
Yeah... if you want to put the cam and lifters at risk.

Personally I wouldn't attempt to start that engine until you are ready to run it at high rpm for 20 min's or so as you are depending upon the oil thrown off of the crank and rods to adequately lubricate the cam lobes and lifters until they break in.
