The Super Chevy article states that Fran Preve has Tonawanda documents that list the 1968 MV code 396 as a "CONV L78 COPO F BODY". They speculate that this was "Pigginese" for hiding a special 427 engine installation. This would not be the only time Chevy would spec out a L78 but install a L72. Chevy also did this with the COPO Chevelle. In the option field of the COPO 427 Chevelle build sheet it lists a "L78 396 4BL-V8". The L72 or the 427 is not indicated on the build sheet unless you can decode the 9562 or the engine code box. The COPO guys were hiding the 427 engine in the codes. Maybe they did this on the 68 Yenko Camaro. Maybe they didn't but it was possible to do. The Chevy Action article states that two 68 Yenko Camaros have been found with original MV code 427 engines with a "321" casting number and they also have the POP with the MV code. The COPO document is also shown. Of course, just because it is in a magazine doesn't make it true but this is what they claim.
