How many pace cars were made with Option MM4

Dear pacecarguy-- There were 6,502 Indy Pace Corvettes sold in 1978. Originally Chevrolet planned to build 2,500, but demand was so great that they built more. Even at the higher production number, The Wall Street Journal advised their readers that buying one was a good investment. As for the MM4 transmission, it was not listed as an option until 1979. Two good Corvette sites to browse through are http://www.rogerscorvette.com/specs/78.htm and http://www.100megsfree4.com/corvette/1970/vet78.htm. Good luck from Bovan.
