NOTES:

  • An LS7 engine rated at 460 horsepower (or 465 horsepower) was planned to be included as an option, and GM went as far as to list it in the vehicle order guides.  The LS7 was to be a big-block version of the LT1, including aluminum heads.  A ZR2 package with the LS7 was also planned.  The suffix for the LS7 was assigned as CZL for manual, CZN for automatic.  The LS7 and ZR2 were canceled and it is believed that none were delivered to retail customers.
  • Big block engine displacement increased from 427 cubic inches to 454 cubic inches.  The small block engine displacement remained the same at 350 cubic inches, although the new LT1 engine option included solid lifters and was rated at 370 horsepower.
  • The 1970 model year included the lowest production numbers of any Corvette since 1962, due in part to an extended production run of the 1969 model year.
