At last Sunday's show, one of the "stock" entries was a beautiful 1969 Mach 1. I was surprised to find a Cleveland 351 installed because I had always thought that the 351-C was started in the 1970 production. This was a San Jose car and the owner said had a July 69 build date (the end of the 1969 model year). So could this be legit? And if so, how many 69's were built with Cleveland 351s?
