Chevrolet’s newly upsized 454 CI big-block engines may have grabbed the headlines for 1970, but the potent, new LT1 small-block engine was also available for the Corvette, initially delivering a factory-rated 370 HP. Featuring all the right features for high performance and durability, the high-winding LT1 mill was based on a high-strength cylinder block, with the forged crankshaft supported by 4-bolt main caps. Built to perform with a hot solid-lifter cam and valvetrain, the LT1 breathed deeply through free-flowing cylinder heads with 2.02/1.60 inch valves, as well as low-restriction intake and exhaust systems. Affectionately called “the mouse that roared” by none other than Corvette Chief Engineer Zora Arkus-Duntov, the LT1 delivered big-block performance with low weight, ensuring the Corvette’s great handling. Importantly, the LT1 often slipped under the purview of increasingly watchful insurance companies. Just 1,287 of 17,316 Corvettes left the factory with the $447.60 LT1 option for 1970, and all examples extant today remain highly collectible and enjoyable. Sold new at Palmyra Motors Inc. in Palmyra, New York, this LT1-powered 1970 Chevrolet Corvette Coupe is offered with the odometer showing just 13,955 miles. Powered by the formidable 350/370 HP LT1 V-8 engine, paired with a Muncie M21 close-ratio, 4-speed manual transmission, this striking Donnybrooke Green Corvette is accented by a Saddle vinyl interior. Other features and options are numerous, including T-tops, a tilt and telescopic steering column, power steering, a Delco AM/FM pushbutton radio and Rally wheels mounting period-style Goodyear F70-15 wide-tread tires. Awards and accolades under NCRS judging include Top Flight, Performance Verification, the Duntov Mark of Excellence award and a 5-Star Bowtie award. Part of the 2006 NCRS Gallery VI at Corvettes in Carlisle, this rare, highly decorated 1970 Chevrolet Corvette LT1 Coupe comes with outstanding documents including award certificates and judging sheets, plus the order form, sales invoice, Car Shipper manifest and a letter from legendary Chevrolet General Manager John Z. DeLorean.
