1970 Chevelle SS L78 ?
 

There is a discussion on Team Chevelle about this car that is purported to be an L78. It is Canadian built, but so far, no pics of the trim tag to verify. The VIN does indicate Canadian and there is a lot of paperwork in an old ad for the car. Just wondering if anyone on here knows of the car or if it is in the registry. The engine in it now appears to be an L34.

Oshawa did not build any solid lifter cars.

Thanks Rick, I knew there no LS6's built there, but am not knowledgeable on the L78. Seems the conversion got sideways and someone besides the OP mentioned an L78. Car is currently advertised as an L34.
