Six Cylinder: Passenger side of the block behind the distributor.

The prefix portion of the ID code tells you the assembly plant code, and the engine's production date (for example, 0701 = July 1st....no year is indicated). The suffix portion tells you the original model year / engine / transmission / car combination when it went down the assembly line

Well, because your answer was so close to not-even-close, I went elsewhere. Thank you for NOTHING!
