It was on ebay back in 07, so looks like they still have it.

Complete 1968 Z/28 Camaro MO code engine for sale. This is from a car that was not numbers matching and was turned into a pro-touring street machine. It is a good running engine that appears to have been recently rebuilt. The frame, four piston disc brakes, and muncie four speed transmission is included. Also has power steering with deep groove pulleys. This is a very rare, hard to find engine.

This set up is excellent for a 1968 Z28 clone or perfect if you have a real Z/28 needing the drive train. $7500 or may trade for a First generation Camaro needing restored or a 1968 Firebird. I will also consider a 1969-1970 Dodge Charger in trade. Note: rear end in picture is not included.
