1970 CHEVROLET Corvette 454- Cortez, Colorado

This 1970 Corvette was listed for sale on the Hemmings website in 2014. The so called 'C3' bodystyle of the Corvette is popularly known as 'The Shark' style because it was based on the Mako Shark II showcar. The regular production Shark was introduced for the 1968 model year and received some tweaks for 1969. The 1970 model year saw some noticeable alterations to the body. Fender flares were added to the wheelwells to reduce chips in the paint due to rocks being thrown up by the wide tires. The vents coming our behind the front wheels received an egg crate style insert which matched the new front grille design.

The 1969 model year of the Corvette (and also the Camaro and its twin, the Firebird) was extended into early 1970. The 1970 Corvette model year ran from January, 1970 until fall, 1970 which left little time to build and sell 1970 model year Corvettes. Not surprisingly, the result was a low production run of 17,316 cars.

The original owner bought this Corvette towards the end of the 1970 model run. He bought this Corvette new from Lohmann Motors Inc. in Miles City Montana on September 3, 1970. At the time he was 28 years old with a good career as a petroleum engineer. Over the years he purchased many collector cars but always held onto the Corvette despite minimal use after 1980.

The Corvette is painted code 982 Donnybrook Green paired with a code 424 saddle tan custom leather interior. The custom interior provides leather seat covers, thicker carpeting, wood grain applique in door panels and console and carpeting on the bottom of the door panels. The leather was available in either black or saddle.

Comfort options are minimal: U69 AM/FM radio and the rear chrome luggage rack. No power steering, no power brakes, and no A/C.

The rest of the options are all high performance oriented: the LS5 454 390 HP engine, M21 4-speed close ratio transmission, YE1 special 3.70:1 axle ratio Positraction all mean business.

The VIN 194370S415109 decodes:

1= Chevrolet

9= Corvette

4= V8 Engine

37= Coupe

0= 1970 Model year

S= St. Louis, Missouri final assembly plant

415109= Sequence number

1970 was the first year for the optional 454 engine which was created by putting a stroker crank into the 427 block. The 454 engine stats were printed on a plate in the console which informed drivers that their engine had 10.25:1 compression ratio, 390 HP and 500 Ft Lbs of torque. Although the optional LS5 454 engine had more cubic inch capacity than the optional 427 of prior years it used a low riser intake manifold which cost a few horsepower at the very top of the RPM range. Some musclecar fans lamented the loss of the 427 but the extra cubes of the 454 created a very flexible engine that effortlessly performed where other engines worked much harder to accomplish the same result.

The owner noted the numbers on engine block pad: T0702CZU, 70S415109.

The original owner's Corvette purchase corresponded roughly with his marriage. The new couple took the Corvette north to Banff, Alberta for their honeymoon. The Corvette was in Montana for 12 years, then spent 3 years in Wyoming when they moved. When the couple moved to Colorado in the early 1980s the car was still titled in Wyoming. At this point in spite of the manual shift and lack of power brakes or steering the owner's wife was driving the Corvette more than he was!

The Corvette is all original except for a repaint in 1974. Unhappy with the way the factory paint job was wearing, the owner had the body stripped and painted back to original color and paint type. The car has never been damaged and always stored inside.

Owning a fleet of collector cars and buying and selling classic cars allowed the Corvette to be driven occasionally using a dealer plate but for all intents and purposes it was not driven much once the move to Colorado was made. It shows 58,407 original miles in 2014 with the majority of the miles accumulated prior to 1980.

The owner describes his car as,

"Very tight and drives as good as when I bought it new."

In recent years new tires, brakes, exhaust and a throwout bearing were replaced on the car. Fiber-optics, vacuum operated wipers and headlights work as new. The car still has the original window sticker, protect-o-plate and T top covers that came with the car when new. Now that he is 72 years old the original owner is paring down his car collection, including his one owner Corvette. On Oct 25, 2014 the car was sold. The original owner had the car 44 years and 52 days.
