A lot of cars claim to be the birth of the niche they occupy. There are many imitators, but in the muscle car category, the Oldsmobile Super 88 is that unicorn. The Rocket 88 engine was the first time the formula of "shoving a large overhead valve engine under the bonnet of a large American passenger car" was used to great effect in order to create what you or I would ostensibly call a muscle car.
The Rocket engine was GMs attempt to give Oldsmobile something special to compete against the goliaths at Ford and Chrysler but instead gave rise to something far more culturally significant. We think it's important that every petrolhead understands why this engine means so much to the car culture we know and love today.
Today, let's take a special trip back in time to appreciate the icon that is the Oldsmobile Rocket 88 engine, and why without it, muscle car culture may look very different today.
Speeding Up The World
The 40s and 50s were times of breakneck change in America. In 1956, President Eisenhower authorized the use of $25 billion in federal funds towards the completion of a national highway system that would be second to none in the developed world.
Sure, these roads were initially envisioned to transport U.S Military tanks and soldiers quickly (Eisenhower was an ex WW2 general after all). But an unexpected side effect was suddenly, it was possible for someone to hop in their car, get on the George Washington Bridge in New York City, and take that one highway, now called Interstate-80, all the way to the Golden Gate Bridge in San Francisco without getting off that road.
Not only did you never have to get off this road except for bathroom breaks if you didn't want to, but you could also cruise this road at 70 to 80 miles per hour when most geriatric old state routes had a limit of 50 or so. Before their eyes, the world was getting a lot smaller for these children of the 40s and 50s. and these spry young people needed cars with engines capable of driving across these new multi-lane highways at high speed, enter the Rocket 88.
The Oldsmobile Super 88
The Rocket 88 engine is so celebrated these days that people often refer to the Olds Super 88's they came in as Rocket 88's. As mundane as it sounds now, overhead engine valves were advanced in their day the same way active fuel management may be in today's engines. Sure, flathead engines could make good power reliably, but having engine vales directly accessible underneath the engine valve covers meant making big power was not only doable but even easy.
Limited edition 303 cubic inch original Rocket 88s with four-barrel carburetors could make 160 hp and healthy 265-pound feet of torque. That may not seem like much when your average hot hatchback these days can make similar figures. But remember, in the mid-1950's most cars were lucky to make even half that, and they'd have a really hard time getting up to speed on new American interstates, but not the Rocket 88.
King Of The Interstate
The Rocket 88 would see consistent improvements over the next two decades or so. Displacement swelled from 303 Ci or 5 liters all the way to the gargantuan 455 Ci 7.5 liter V8 in the early 70s. Even still, the same design philosophy carried with it throughout its production run.
You see, the rocket 88 is not a racing engine, it's not even a performance engine for that matter in the same vein we may laud a BMW M5 today. This engine was built for one purpose and one purpose only. The ability to do left lane overtakes at any speed, in just about any gear.
As the cars the Rocket 88 was put in got larger and larger, it was clear that they weren't going to be participating in Pike's Peak anytime soon, but then again, it didn't have to. The Delta 88s of the 60s and 70s were big family cruisers in the ultimate sense of the word. absurdly long wheelbase and curb weights became a hallmark of most American cars from this time period, and the Rocket 88 engine was just the engine for the job.
The Birth Of The Muscle Car
GM may not have known it at the time, but the Rocket 88 was destined to change American car culture forever. Before it, big horsepower was a privilege reserved for the wealthy and well to do in their Bentleys, Jaguars and Duesenbergs. Afterward, the Muscle car revolution made insane horsepower available to any man or woman who wanted it.
This extends far beyond muscle cars of the 60s. Think the Charger Hellcat was the first time Americans tried to shoehorn a massive engine into a family sedan? The Rocket 88 was doing that before anyone who designed the Hellcat was even born. So let's pour ourselves a drink and raise a toast to the Rocket 88. Our lives as petrolheads would be much more boring without it.
