For the record, this was a running engine. It drove into the garage, the day it was pulled. The harness is indeed complete, and in complete running order. The head gasket had just went, engine never overheated. During teardown to change the head gasket, we found it needed a timing set as well. To speed up the process of getting it running, we just swapped the engine with a running one. The distributor was missing from that one. Engine has a complete 87 EFI plenum and sensors included. Perfect working order. Heard the engine run, before pulling it for his truck. Good engine for the money.
