This is a 427/425 original car. That is to the best of my knowledge this is the engine that this car left the factory with. The car is 90% original. I just had the engine rebuilt to factory specs including cam and compression ratio. New clutch, the old one disintegrated and blew apart right through the bell housing. The bell housing is from a ’67. The car was restored about 9 years ago. The previous owner did a frame off about 20 years ago using Nolan Adams Corvette restoration and Technical Guide book as reference. The interior is new from Al Knoch. The top is a new date coded replacement. I have the original steel wheels and hubcaps, but right now it has reproduction ’66 knock offs. Rebuilt original transistor ignition.
