1970 Chevrolet Chevelle L78 Convertible

In 1970, Chevelle SS buyers could opt for four engine choices: the 396/350 HP L34, the 396/375 HP L78, the 454/360 HP LS5 or the monster 454/450 HP LS6. With so many choices, buyers who were sold on big-block horsepower usually opted for the massive LS5 or LS6. Other buyers who gravitated to the proven 396 usually checked the box for the 396/350 HP option. The 396/375 L78, which was being phased out by GM in 1970 and was only offered as an option for several months, may have been overshadowed by the arrival of the now legendary LS6 454/450 HP big-block V-8, but the L78 remained as potent as ever, packing beefy forged internals, a radical solid-lifter camshaft, a Holley 780 CFM 4-barrel on a Winters aluminum intake manifold, free-flowing heads and one of the sweetest exhaust notes of any contemporary muscle machine.

This 1970 Chevrolet Chevelle L78 Convertible is one of few ever built and one of only a handful with its impressive level of GM documentation. It was ordered new in Code 75 Cranberry Red with white racing stripes and a white vinyl top, which was complemented by a black, vinyl bucket-seat interior. It’s powered by the L78 396/375 HP big-block V-8 engine, which channels power through an M21 4-speed transmission package and 4.10 Positraction rear axle, and it’s equipped with power steering, power front disc brakes, a power top, console, engine block heater, F41 suspension and a cowl induction hood.

Due to the rarity of this beautiful Chevelle L78 Convertible, a comprehensive frame-off restoration was warranted. The body and paint is exceptional, having been wet sanded and polished, and the engine compartment is detailed correctly to how it would have left the factory. The undercarriage has been painted in the correct satin black finish, and suspension components were detailed as well. The most important aspect of this car is that it comes with GM of Canada documentation proving how it left the factory when new. Documented examples are extremely hard to come by, making this example a great addition for any collection.
