1970 Corvette

1970 Chevrolet Corvette Coupe


The C3 Chevrolet Corvette debuted in 1968 and lasted until 1982.

1970 Corvettes had a new silver egg-crate grill with larger, rectangular signal lights. The signal lights had clear lenses and amber bulbs. The front fender louvers were changed to one large opening with a matching egg-crate style grill.

The rear edge of the wheel well openings, both front and back, now had built-in fender flares to better cover the eight inch wide tires and to protect against stone chips. Exhaust pipe tips at the rear of the car were now rectangular.

The seats were redesigned and were taller with built-in headrests and shoulder belts.

The base 350 engine remained the same and was still rated at 300 horsepower and 300 foot-pounds of torque. 1970 was the first year of the original LT1 engine with 350 cu in displacement, 370 hp, and 380 ft-lbs of torque. The 427 was gone, and so were the L88 and ZL1 engine options. The 427 was replaced with a 454 cubic inch Chevy big block, rated at 390 hp and 500 ft-lbs of torque (LS5), or 465 hp and 490 ft-lbs of torque (LS7). Reportedly, no LS7 Vettes were sold.

1970 would mark the highest rated horsepower and torque ratings for any Corvette until the 2006 Z06.

1970 Corvette Key Differences

1970 and 1971 Corvettes had front signal lights with clear lenses which set them apart from 1972 Vettes which had amber lenses.

'70 and '71 Vettes are virtually identical but can be differentiated by the chrome trim strip surrounding the front grill. In 1970, only one screw is visible from the front, unlike 1971, when three screws are visible.

Another difference is the engine specifications plaque mounted on the central console. 1970's Corvettes have 10.25 or higher compression ratios, while 1971's have 9.0 or lower compression ratios.

Similar Years

1970 to 1972 Corvettes are very similar and have the same egg-crate front grill and side louvers, the same rectangular front signal lights, and the same chrome bumpers front and rear.
