The editor of Sports Car Graphic drove it for 2500 miles and found it did the quarter mile in 13.8 seconds at 108 mph. GM cancelled the option even though the LS7 option is listed in some early 1970 sales literature. None were ever sold. 70.5 % of 1970 Corvettes were sold with four-speed manual transmissions 33.5 % had tilt steering wheels 27.9 % had power windows 38.5 % had air conditioning 68.8 % had power steering A 1970 Corvette with the L56 engine could do 0-to-60 mph in seven seconds and go from 0-to-100 mph in 14 seconds A 1970 Corvette with the LT1 engine could do 0-to-30 mph in 2.5 seconds, 0-to-60 mph in 5.7 seconds and go from 0-to-100 mph in 13.5 seconds A 1970 Corvette with the LT1 engine could do the quarter mile in 14.17 seconds at 102.15 and had a top speed of 122 mph 1970 CORVETTE Click here for Corvette books Books on other automobiles Dictionary of over 15,000 Automotive Terms Cadillac History Sign My Guestbook View My Guestbook a@motorera.com 1962 1963-67 overview 1963 1964 1965 1966 1967 1968 1969 1971 1972 1973 1974 1975 1976 1977 1978 June 18, 1999
