The story of the 1949 Olds Rocket V8 engine has been told countless times. So let’s shift gears and explore the Oldsmobiles powered by the new V8 in ’49.

Series 76 Club Coupe 

At the Oldsmobile division of General Motors in 1948-49 things were moving pretty fast, with events that often didn’t align with the Motor City’s annual model change traditions. In February of 1948, one full month after the rollout of the rest of the 1948 Olds model line, came the redesigned Oldsmobile 98 with its all-new Futuramic styling theme—the first postwar exterior design from the Lansing division.

Then September of ’48 saw the launch of the ’49 Oldsmobiles, now featuring Futuramic styling across the product lines, including the A-body Series 76. With them came the release of the sensational Rocket overhead-valve V8 for the 98, which began driving out of the showrooms in December. (See our feature here.) But wait: Oldsmobile wasn’t done yet.

On February 6, 1949 Olds put out a press release announcing the Series 88, which combined the game-changing 303 cubic-inch Rocket V8 with the smaller Series 76 platform. With its six-inch shorter 119.5-in wheelbase, 300 lbs less weight, and a foot less overall length than the 98, Olds had created a factory hot rod. Tom McCahill of Mechanix Illustrated declared the 135-hp 88 the new king of the road, noting the 12.0-second 0-60 mph times. Bending the rules a bit many years later, some observers claimed the 88 was the first Detroit muscle car.

Also in February of ’49 the 98 Holiday Coupe arrived (lead photo top of page). Oldsmobile’s first pillarless hardtop, it shared a GM C-body shell with the Buick Riviera and Cadillac Series 62, which in turn were based on the C-body convertible. As the Olds division flagship, the 98 Holiday offered an impressive list of standard equipment: Rocket V8, Hydra-Matic transmission, power hydraulic window lifts and front seat adjustment.

Series 76 Big Six

Totally overshadowed by the new short-stroke V8, understandably, was a new six-cylinder engine for the Series 76, the 257 cubic-inch Big Six. Actually, this was the familiar Olds 238.1 CID L-head six bored and stroked to the limit (3.53-in bore; 4.38-in stroke) to match the displacement of the previous Olds straight eight, discontinued with the introduction of the Rocket V8. With a 7.25:1 compression ratio and a Carter single-barrel carburetor, it was rated at 105 hp. The Big Six was offered for just two seasons, though, as in 1951 Olds went to an all-V8 lineup.

There was one more mid-season change-up at Oldsmobile in ’49, on the Series 76 and 88 station wagons. When the model year began, wagons were of traditional wood construction with mahogany panels and maple framing. Then halfway through the production run, Fisher Body switched to all-steel construction, using paint and Di-Noc film to mimic wood. Wagons were not a big part of the story in 1949, accounting for barely one percent of the volume, but Oldsmobile had a great year anyway, selling nearly 290,000 cars.
