Rarity, performance and historical significance are the dominant themes of Milt Robson’s car collection. These are not mainstream machines; they come from the exciting fringes of their eras. At one extreme are the “strippers” – those drag racer specials marrying the cheapest, lightest bodies with the most powerful engines available. On the other side of the bell curve lay the glamour models – the plush, well-equipped top-drawer cars with the biggest big-blocks and price tags so large that low production numbers were virtually guaranteed.
After a four-year run as a stand-alone series, the 4-4-2 became a $29 cosmetic-and-handling package (indicated on build sheets as the “W-29”) for the 1972 Cutlass and Cutlass S coupes and Cutlass Supreme convertibles.
The W-29 included the FE2 suspension components (heavy-duty springs, heavy-duty shock absorbers, front and rear anti-sway bars, boxed lower control arms, and 14x7-inch wheels), unique stripes and badges, non-functional hood louvers and a package-specific grille. Sporty cutouts in the rear bumper accommodated dual exhaust outlets if ordered with big-block power.
Cutlass 4-4-2 hardtops featured stripped-down interiors with a two-spoke steering wheel and a vinyl or cloth/vinyl bench seat with rubber floor mats. Cutlass S 4-4-2s had the deluxe steering wheel, full carpeting, courtesy lights and a variety of seat choices, including the upscale Strato buckets to which a buyer could add an extra-cost center console.
Because GM stopped advertising its engines’ “gross” ratings with the 1972 model year, the base 4-4-2’s 350-cu. in. two-barrel V-8 produced 160 “net” horsepower. For $47, a buyer could gain an extra 20 horsepower with the L-34 four-barrel 350. Big-block motivation came in the form of an optional $188 455-cu. in. four-barrel L-75 V-8 that produced 270 net horsepower and 370 lb-ft of torque.
Checking the W-30 box on the order form brought the $648 L-77 engine – a 455-cu. in. four-barrel with low-restriction exhausts rated at 300 horsepower and 410 lb-ft of torque under the new rating system. With its aluminum intake manifold, functional fiberglass intake hood (W-25), heavy-duty cooling system and 3.42:1 rear axle gears, the W-30 powerplant was every bit as potent as the previous year’s 350-hp V-8.
The W-30 455 could be ordered as a Cutlass hardtop coupe or Cutlass Supreme convertible and was mated to a four-speed manual or three-speed automatic transmission. According to T. Patrick Sullivan’s excellent book Oldsmobile 4-4-2 and W-Machine, of the 9,845 4-4-2 (W-29) packages ordered in 1972, 1,171 were convertibles. Only 113 of the 4-4-2 convertibles had the desirable W-30 engine, and only 33 of those were powered by the four-speed manual. Air conditioning could not be ordered with the W-30 option, and power brakes were only available when paired with automatic transmissions.
This car was auctioned off by RM Auctions in November of 2010 at the Robson Estate, Gainesville, Georgia.
