what is in the engine of a 1966 chevrolet corvette?
Plenty of horsepower, as long as there's gas in it, lilhardy. If you meant what kind of engine is in a '66 Corvette, there were a number available. The base engine was a 327 cubic inch, 300-horsepower engine. Options included a 350-hp, 327-ci engine; a 390-hp, 427-ci "big block"; and a 427-ci "big block" that was rated at 425-hp, but probably produced 500+. Hope that helps!
