Lot #361.1 - This rare special-order Heavy Chevy was marketed as a lighter version of the SS and advertised much lower stated horsepower as an insurance beater. Heavy Chevys were factory coded as a base Chevelle and theoretically avoiding the SS title, which triggered staggering double digit insurance premium increases in the early '70s. The factory RPO code YF3 made this a rare Heavy Chevy and was a sub-model based on the Chevelle series. It features a blacked-out grille and headlamp bezels, 14x6" Rally wheels with bright center caps and no trim rings, a domed hood and hood pins, lanyards and full-length Heavy Chevy body stripes and hood and trunk lid and fender badges. It's also equipped with F41 heavy-duty suspension and a base interior including rubber floor matting and bench seating to save weight. This Heavy Chevy is one of only 286 built with the optional big-block LS3 402ci engine (the largest engine available) and the special heavy-duty MC1 Muncie 3-speed manual transmission that was only available with this engine. Additionally, it was ordered with front power disc brakes, sport steering wheel and posi-traction rear axle. A true one-owner car, it was built in Arlington, TX, sold at Vandergriff Chevrolet in Arlington and has been in Arlington its entire life. This is an all matching-numbers car that comes with a copy of the original sales agreement, warranty book with Protect-O-Plate, pre-delivery vehicle inspection form, special-order deposit receipt, original owner's and emission manuals, and an original dealer's brochure from selling dealership. It was originally special-ordered on March 11, 1972, and delivered on April 17, 1972. The original owner wanted the top performance options available but with air conditioning. With only 9,508 total Heavy Chevys built in 1972 and super rare, this is one of only 286 Heavy Chevys built with the LS3 big-block engine and MC1 special heavy-duty Muncie 3-speed manual transmission.
