1970 Corvette LT1
1970 Corvette LT1
This 1970 Corvette LT1 only has 2202 original miles and it is considered to be one of the finest examples of a 1970 Corvette LT1. Even after the introduction of the Mark IV big-block engine in the Corvette lineup, the small-block Corvette nurtured by engineer Zora Arkus Duntov always accounted for the majority of Corvette sales. The wheezy 265/195 HP offering of 1955 bloomed under Duntov’s efforts into the 327/375 HP L84 “Fuelie” of 1964-65, but until 1990 the most powerful carbureted small block ever packed into a Corvette was this car’s solid-lifter 350/370 HP LT1.
Corvette number 250,000 rolled off the assembly line in 1969, but the celebration was muted by the need to continue improving the third-generation Corvette. Alarmed by the motoring press’ response to the new Stingray, John DeLorean resolved to make quality control the Corvette group’s top priority. The 1970 model had been delayed four months by a factory strike, and the new inspection regime slowed production even more. Teams were mandated to correct any fault before sending a car on its way. Every car was subjected to a pressure water bath to expose any leaks after which they were driven over a cobbled road and then placed on a vibration table to reveal any creaks or other noises caused by flexing. While few external revisions were made, interiors were upgraded in the first of several steps to add more luxury to the Corvette mix. The seats were redesigned to add headroom and ease access to storage, and a deluxe interior with leather seating, woodgrain trim and deep pile carpeting was offered for the first time. In 1969 the 327 CI small-block V-8 was replaced with the L46 350 CI version employing a Rochester four-barrel carburetor on a cast iron intake manifold, a hydraulic cam and 11:1 compression to achieve 350 horsepower; in 1970 it was joined on the option list with the LT1, which used racing-grade internals, a solid-lifter cam, a Holley 780 CFM four-barrel carburetor on an aluminum dual-plane intake and high-flow heads. The LT1 was rated at 370 HP at 6,000 RPM, once again shrieking that distinct banshee howl that had always characterized the high-revving small-block Corvette.
This unrestored 1970 Corvette coupe is one of 1,287 built with the mighty LT1 small-block V-8, which was available only with either the M21 close-ratio or M22 close-ratio heavy-duty 4-speed manual transmissions; here it is teamed with the M21 and a high-stepping 4.11:1 Positraction rear end. Sold new at Gene Merollis Chevrolet in Garden City, Michigan, it remains exactly as it was delivered with its original Mulsanne Blue metallic paint and matching Bright Blue interior, arguably one of the most enticing color matchups of the third generation Corvette. At a mere 2,202 original miles, it is as original in practically every aspect as any example still in existence, as evidenced by its induction into the Bloomington Gold Great Hall and Bloomington Gold Certification. It was also decorated with the NCRS Top Flight Award with a 99.6. In addition to those prestigious achievements, it also received the Chevy Vettefest Triple Crown in 2003. This practically perfect LT1 coupe is documented with the original tank sticker, Protect-O-Plate, retail order form and salesman’s business card, and the original keys and owner’s manual.
