In the late 1960s, Oldsmobile got the groovy idea to create the fictional mad scientist Dr. Oldsmobile, a lab coat-wearing hype man for the brand's powerful 4-4-2 and W-machines. But truth be told, Olds muscle cars didn't need much help — 1964's modest 4-4-2 performance option had grown into a 455ci V8-powered monster by 1970.
Built on a sturdy A-body perimeter frame, the 1970 4-4-2 was available in two-door post Sports Coupe, two-door hardtop Holiday Coupe, and Convertible bodies. And all featured round, beautiful styling with a unique grille, dual exhaust tips, and special badging, along with a premium interior, which helped separate the 4-4-2s from regular Cutlasses.
The big news was 4-4-2’s massive 455ci V8, which produced a mind-bending 500 pound-feet of torque and 365 horsepower. Backed by a manual or automatic transmission, a heavy-duty suspension, and 14-inch wheels wearing soon-to-be bald performance tires, the 4-4-2 was both greatly admired and greatly feared on America’s boulevards. With only 2,933 1970 Convertibles leaving the factory that year, 4-4-2 drop tops were both fast and rare.
This convertible has been refinished in red with black stripes, and wears black upholstery with a matching top. The 455 is said to be a 396021F block with E heads, and wears light modifications including an Edelbrock intake manifold and ceramic-coated headers. The carb has been rebuilt, with the big block being fired with an HEI distributor and fresh spark plugs. A Hurst shifter commands a previously overhauled three-speed automatic transmission.
This 1970 Oldsmobile 4-4-2 Convertible is now offered on dealer consignment with a clean Florida title.
