I would mostly be interested in this "rebuilt" motor. "Had timing problems" leads me to believe the IMS failed. If it was truly rebuilt with a new IMS (ideally not a new stock piece), new bearings, appropriate headwork, and ideally, sleeved case halves and forged internals, then that should be a great motor.
If it was all done half assed, then, well.....
