Competition is a great thing, especially in motorsports, as it, inevitably, graces us with astonishing powertrains. One such race-derived American V-8 is the Ford 427. The engine is part of the Ford Y-Block series and comes in a few different versions. The most notable of them is the 427 side-oiler, which was featured on the Shelby Cobra 427 S/C. Another 427 variant was the SOHC “Cammer”, which was meant to beat the 426 Hemi cars in NASCAR.

In 1961, Buick developed a new small V-8 that would come to power Oldsmobiles and Pontiacs but would never sit in the heart of a great American muscle car. So why is it so special you ask? Well after General Motors had finished with the engine, they sold everything to do with it to the British automotive company Rover.

After Ford tasted success with their initial V-8, they never stopped chasing glory. They were hooked on the configuration and continued updating their offerings. In 1961 they came out with the first in the Windsor family. The first of the 5.0-liter mills arrived later in 1968 to fulfill the regulations of the Trans Am racing series, in which five liters was the maximum displacement.

Before the mighty 426 Hemi, Chrysler gave us the 426 Max Wedge. The Wedge-head B-block design started in 1951 with a 331 cubic-inch variant, until eventually, displacement grew to 426 cubic inches. Like its successor, the 426 Hemi, the 426 Max Wedge was all about racing. The engine was designed for Super Stock racing and featured a compression ratio of 11:1 to 13.5:1 depending on the application.

One of the biggest American V-8 engines put in a production car wasn’t meant to be a performance engine. The 472 was exclusively meant for Cadillac’s full-size luxury models like the DeVille and Fleetwood. Despite featuring an oversquare design, with a 4.3-inch bore and 4.06-inch stroke, the engine was a low-revving lump, meant to produce massive, low-end torque – something that was needed to propel the nearly-5,000-pound luxury barges it was put in.

In 1970, Cadillac introduced a 500 cubic-inch variant of the same engine, featuring a different crankshaft for a longer stroke of 4.304 inches. This was good for another 25 horsepower and slightly more torque, although 1971 would see a sharp decline in performance due to smog regulations. Ironically, it is Cadillac that currently, offers the most analog and driver-centric V-8 sedan on sale.

10 Chevy Muscle Cars That Featured The Iconic Small Block V-8

Here’s how the Chevy small-block V-8 engine pushed some of the most iconic cars on the planet to stardom!

6 Buick 455 High Output

Production Years: 1970-1976

Buick is one of the lesser-likely names to appear when we talk about American Muscle cars, despite making a ruckus in the 1980s, with the GSX. Still, in 1970, the brand that was known mostly for making old-man’s commuters came up with a real showstopper that could easily run with the Chrysler Hemi and Chevy Big-block-powered models. The Buick GSX Stage 1 was based on the rather mundane Skylark, but it packed a 455 High Output V-8.

Noteworthy Application

Buick GSX Stage 1, Buick Riviera

The 455 H.O. benefited from new heads with bigger valves, a new intake, beefier internals, and a tweaked carburetor. It was also criminally underrated at 360 horsepower in its earlier versions. The 455 H.O. Stage 1 also packed the most torque of any Muscle car. Only Cadillac’s 472 and 500 cubic-inch engines produced more torque than the Buick 455 H.O.

5 Chevrolet 454 Big-Block

Production Years: 1970-2001

Back in the 1960s and 1970s, few things were cooler than a Big-block Chevy V-8, and back then, the 454 Bic-block was the King of the hill. Of course, there was the L88 427, which we already mentioned, but the only application, where it made more power was in competition spec. The 454 was, typically, reserved for full-size Muscle cars like the Chevrolet Chevelle SS, but also, the C3 Corvette, from 1970. The 454 came in a variety of power levels, but the most notable was the LS6, which is what the Chevelle SS 454 came with.

There was also an LS7 version of the 454 Big-block, but very few were made. The 454 was a simple engine and while it didn’t feature hemispherical combustion chambers like other American V-8s on this list, it was a very robust unit. It was in production until 2001, and since the bore and stroke were never altered, parts are interchangeable.

4 Pontiac 455 Super Duty

Production Years: 1973 – 1976

The largest engine ever produced by Pontiac was in 1970 when they released the 455 V-8. A high-output 455 was released in 1971. The 70s saw a complete shift in the way engines were built due to shifting emissions laws, Pontiac was the last standing and held out with the detuned Super Duty 455 until 1976.

Noteworthy Application

Pontiac Firebird, Pontiac Trans Am, Pontiac Formula

Whilst the 455 Super Duty was not Pontiac’s most powerful 455, it produced an insane 500 pound-feet of torque. This engine represents Pontiac’s last stand against regulations which aimed to get rid of big block engines and would ultimately lead to a hiatus for muscle cars in general.
