In answer to Pontiac’s success with the GTO in 1964, Oldsmobile developed the 442 option later that same year for the intermediate F-85 Cutlass. Signifying the car’s four-barrel carburetor, four-speed manual transmission and dual exhaust, the ‘442’ designation announced a serious performance car with a unique combination of blistering performance and upscale panache. A major restyling for 1968 introduced a handsome new aircraft fuselage-inspired design theme and that year, the 442 gained new status as a separate series within the Oldsmobile model line-up.

From 1966, the ultimate performance 442 was equipped with the optional W-30 performance package including a highly efficient cold-air intake system, high-lift, long-duration cam, and many more performance engineered modifications. For 1970, Dr. Oldsmobile unleashed the ultimate W-Machines with the massive 455 cubic-inch V-8 now available. Advertised at 370 under-rated horsepower and delivering an impressive 500 foot-pounds of torque, the new W-30 442s inhaled fresh air through the new W-25 – Forced Air Induction system with the twin-scooped Outside Air Induction (OAI) fiberglass hood. In addition to all the high-performance hardware, W-30 engines were carefully assembled using Olds’ Select Fit process that was in essence factory blueprinting with internal components matched by size and weight. The extra care paid off, with W-30 442s tearing-up the quarter-mile with ETs in the high-13s at over 100 mph from the showroom floor. Capable of taking on and beating the quickest and fastest cars of the day, the W-30 442 did it with braking, comfort, handling and style to match its formidable performance.

This stunning 442 was sold new at Oldsmobile-Cadillac dealer John Welgan, Inc., in Saratoga Springs, New York. Once a crown jewel in the famed Buddy Holt Collection, this 1970 Oldsmobile 442 W-30 convertible is one of the rarest machines of the classic muscle-car era. It is one of only 96 W-30 convertibles built in 1970 with a Muncie M21 four-speed manual transmission and its triple black color scheme puts it among a mere handful within that group.

Wanting to perfect and preserve this rare muscle car, the previous owner delivered it to Jeff’s Resurrections in Taylor, Texas, for a nut-and-bolt restoration. After the expert craftsmen there completed their work, the W-30 was entered for judging at the 2006 Oldsmobile Nationals, where it scored 990 out of 1,000 points. Featured in the July 2008 issue of “Muscle Car Enthusiast Magazine,” the car remains in superb concours condition, just as it left Lansing in the spring of 1970. The original matching-numbers 455 cubic-inch is the heart of the W-30, developing 370 HP and 500 lb-ft of torque thanks to high-flow F-code heads, a special cam, a special high-flow Quadrajet four-barrel carburetor on a W455 aluminum intake manifold, high-flow exhaust and a twin-scoop fiberglass hood with sealed forced-air induction system. The M21 four-speed and 3.42:1 locking differential are also original to this all-black beauty, which was also delivered with contrasting red fender liners, front disc brakes, power steering, N67 Super Stock wheels with Goodyear Polyglas G70-14 tires, a tinted windshield, bucket seats and console, a Hurst shifter, a Rocket Rally Pack and an AM radio. Documentation for this exceedingly rare 1970 442 W-30 four-speed convertible includes the original order sheet and invoice from John Welgan, Inc., as well as the original Protect-O-Plate. Simply put, it stands out amongst its peers as one of the very finest available today.
