There is so much that can go wrong on an engine swap (ask NascarNut), its almost impossible to say without seeing it myself. I would say in general to look for any wiring or vacuum hoses that are missing or incorrectly routed, then proceed from there. A vacuum gauge reading can quickly diagnose basic integrity of the motor's internal parts. You can buy one for about $25 at the parts store, and they come with instructions. Basically, you are looking for a nice, high, steady reading at idle, that drops to zero when the throttle is popped open. A vibration or ocillation in the reading indicates a valve, ring, or cam problem, a low reading would mean late ignition timing, jumped timing chain or restricted intake/exhaust path.
