HISTORICAL NOTES

Corvette built only one car with the LS7 engine. 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
