While Chevrolet’s new 454 big-block engines grabbed headlines by 1970, the potent, new LT1 small-block was also available for the Corvette, initially delivering a factory-rated 370 HP. Based on a high-strength cylinder block with 4-bolt mains and forged internals, the LT1 was built to perform with a hot solid-lifter valvetrain and breathed deeply with free-flowing cylinder heads and 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 great handling and often slipped under the purview of increasingly watchful insurance companies. While lowered compression ratios brought gross horsepower ratings down to 330 HP by 1971, performance was essentially intact—even with the switch to stricter SAE net power ratings for 1972; despite a new 255 HP rating for ’72, performance was the same as it was in 1971. Just 1,741 of 27,004 Corvettes left the factory with the $483.45 LT1 option for 1972, the last year of availability prior to the reintroduction of the LT1 option code in 1992. Already quite rare, this LT1-powered Corvette is one of only 1,543 examples produced in Sunflower Yellow paint for 1972. Powered by a matching-numbers, original LT1 engine, options include an M21 4-speed manual transmission and 3.70 Positraction rear end. Benefiting from collector care since 1976, this rare Corvette is offered with 64,951 actual miles. The no-hit body retains mostly original Sunflower Yellow paint, complemented by the original black Deluxe leather interior and white soft top. In addition to an auxiliary hardtop, other desirable highlights include a 1969-style side exhaust, power steering, stainless steel brakes and the A.I.R. smog system. Amenities include an AM/FM/Cassette stereo, audio alarm, tinted glass and Rally wheels mounting raised white-letter radial tires. Most all factory-correct-type components are present, including the spare, jack, jack tools, floor mats, seatbelts, washer system, smog system, shifter, shielding, air cleaner, carburetor, alternator, distributor, window glass, valve covers and fuel-door assembly. Documents include an owner’s manual, sales brochure, the 1976-dated title and CCAS engine block, stamp pad and engine stamp affirmation.
