|1970 Chevrolet Corvette Convertible 454 / 390 hp big block. Very nice 1970 Chevrolet Corvette convertible 454. This is an original, dry Tennessee car. It sports a #'s matching 454 big block V8 and automatic transmission. This is a nice driving, "driver" grade car. It has not been restored, only maintained over the last 38 years. The paint and body are "driver" quality , but not show quality. The interior is pretty original, the only real deviation from stock that I see is that the radio was replaced. The car runs and drives quite well. Just had a tune-up, and the power steering pump replaced. Nice tires, good suspension, engine runs quite well, trans shifts well. Over time, this car will do nothing but appreciate...Big block convertibles are poised to skyrocket past $100k in the next fifteen years. You can jump in and drive it anywhere. Color from the trim plate. 87,501 miles. Motor suffix code is CGW. May 8, 2008.
