The most expensive Corvettes. One to one and a half million

1967, L88, 427 four barrel, aluminum heads. 18 remain.



The L88 with 12.5 to 1 compression, hi-lift cam, 850 CFM 4 barrel carb and aluminum heads was under-rated at only 430 HP. L88s actually have been dyno-tested at 560 HP. How could GM do this without it being called false advertisement? Easy -- the publicized rating of the L88 actually was its true horsepower. Chevrolet just neglected to point out that this horsepower rating was at approximately 1000 RPM under the peak performance RPM of the L88.
