How Fast is a 426 Hemi? 1/4 Mile & 0-60 Results

While reading up on the legendary 426 Hemi Engine, many people wonder how fast it was. I researched the original drag strip results conducted and published when the cars were new. Here are the results.

Here’s how fast a 426 Hemi is in the 1/4 mile race:

  • With an automatic and 4.10 rear gear ratio: the Hemi averages 13.40 sec @ 105.71 MPH.
  • With a 4-speed and 3.54 rear gear ratio: the Hemi averages 13.45 sec @ 105.40 MPH.
  • With an automatic and 3.54 rear gear ratio: the Hemi averages 13.53 sec @ 106.04 MPH.
  • With a 4-speed and 4.10 rear gear ratio: the Hemi averages 13.61 sec @ 106.50 MPH.
  • With an automatic and 3.23 rear gear ratio: the Hemi averages 14.00 sec @ 104.07 MPH.
  • In the 1/4 mile the 426 Hemi’s fastest to slowest time and MPH are 13.10 sec @ 109 mph to 14.10 sec @ 103.20 MPH.
  • From 0-60 MPH the 426 Hemi averages 5.6 seconds.

The above speed test results are taken from automotive car magazine road tests, books and videos when each 426 Hemi was new from the factory.

I included articles from each year the street Hemi was produced and placed them in year order.

Each article is listed below with interesting pictures, funny quotes, videos and facts from the actual road tests conducted.

Therefore, grab your coffee or beer, depending on what time of the day it is and have fun reading.

426 Hemi Race Results Showing How Fast It Is

I gathered every resource, article, video, book and old car magazine available which had original 426 Hemi Road tests.

The resources used include the following:

  • Car & Driver
  • Rodder and Super Stock
  • Car Life
  • Popular Hot Rodding
  • Car and Track
  • Car Craft
  • Super Stock & Drag Illustrated

April 1966 – Car & Driver Magazine – 1966 Plymouth Hemi Satellite

426 Hemi 1/4 mile time and speed with a 4-speed and 3.54 rear gears:

  • 13.80 @ 103.80 MPH

Reading the older articles about the classic cars are usually interesting and this one didn’t disappoint.

Car and Driver drove the Hemi Satellite 700 miles from Detroit to New York. They said they averaged 12.3 MPG, 14 on the highway and about 8 when all 4 barrels were opened up.

They said:

“it takes a lot of gas and a lot of courage to run the Hemi at full throttle for long”

They explained in detail how they launched the car at the drag strip. They found the best way to get the fastest 1/4 mile time was to do the following:

  • Rev the engine up to 1,200-1,400 RPM.
  • Drop the clutch and then floor it as soon as the car was off the line.
  • There’s still PLENTY of wheelspin this way, but it’s much easier to control it this way.

Car and Driver also said they forgot to lower the air pressure in the rear tires which had 35 lbs. of air. In the past they preferred using 18 lbs. of air.

Car and Driver 1/4 mile results for the 426 Hemi (Car and Driver April 1966)

This article proves 1/4 mile times were hurt due to limited traction and the inability to use the engine’s full power off the line.

Another thing holding this car back was the 3.54 rear gear ratio but that’s how the car was ordered.

March 1967 – Rodder and Super Stock Magazine – 1967 Dodge Hemi Coronet R/T

426 Hemi 1/4 mile time and speed with automatic transmission and unknown rear gear ratio:

  • 13.90 @ 104 MPH

November 1967 – Car and Driver Magazine – 1968 Dodge Hemi Charger R/T

February 1968 – Car Life Magazine – 1968 Plymouth Hemi GTX Convertible

426 Hemi 1/4 mile time and speed with automatic transmission and 4.56 rear gear ratio:

  • 13.44 @ 103.5 MPH

Now many of you Mopar fanatics out there is saying to wait a minute, automatic with 4.56 gears?

The article states 3.23 gears were standard, but this car was fitted with the 4.56 ratio. They go on to state, equipping the Hemi with 3.23s is unfair, especially when other manufacturers are providing better ratios.

This article was interesting because they raced the convertible Hemi GTX against another 68 hardtop GTX with the standard 440 engine with 4.30 gears.

This race is living proof when people say a 440 Six Pack would take the Hemi from stop light to stop light. In this case it’s not the Six Pack but the standard 440 with 375 HP.

The 440 took the Hemi off the line but things quickly changed at the 400 foot mark of the 1,320 feet.

The Hemi is seen passing the 440 at 400 feet and then leading by one car at the 800 foot mark. The 440 equipped ’68 GTX ends up with a 13.97 1/4 mile time.

March 1968 – Popular Hot Rodding – 1968 Plymouth Hemi GTX Convertible

426 Hemi 1/4 mile time and speed with automatic transmission and unknown rear gear ratio:

  • 13.85 @ 104 MPH

They put 8″ Goodyear slicks on the car and improved the 1/4 mile and speed to the following:

  • 13.60 @ 107 MPH

The Hemi convertible weighed in at 4,050 lbs. The 440 GTX hardtop in the article was 300 pounds lighter but still couldn’t beat the mighty Hemi.

1969 – Car and Track – 1969 Dodge Hemi Charger 500

426 Hemi 1/4 mile time with an automatic transmission:

  • 14.10

0-60 Times:

  • 0-30: 2.8 sec
  • 0-45: 4.0 sec
  • 0-60: 6.9 sec

Unfortunately, the Car and Track video published didn’t state what kind of rear gears they had. I’m assuming they weren’t 4.10s and probably 3.23s.

Watch the time results and very interesting video below!

1969 Dodge Hemi Charger 500 Race Results and Drifting

January 1969 – Car Craft Magazine – 1969 Dodge Hemi Road Runner

426 Hemi 1/4 mile time and speed with an automatic and 4.10 gears:

  • 13.35 @ 107.39 MPH

*This road test was conducted by Chrysler with Ronnie Sox as the driver.

Besides using the best driver in the world at the time, to make the car run fast they also changed to a cooler spark plug. They switched from Champion N-10Y to UN-12Y.

For a car weighing 3,825 pounds, the Chrysler people were more than happy.

January 1969 – Super Stock & Drag Illustrated – 1969 Plymouth Hemi Road Runner

426 Hemi 1/4 mile and speed with an automatic transmission and 3.54 rear gears:

  • 13.38 @ 108 MPH

The magazine describes how they launched the car:

  • Revved the engine to 1,800 RPM while keeping the other foot on the brake.
  • The gas was feathered for about 75 feet to try and control wheelspin.
  • Pedal to the metal for the remainder while manually shifting the automatic.

At first they kept the car in drive but the times were too slow. By manually shifting the car improved the elapsed time about 4 tenths.

They removed the air cleaner and kept the rear tires at 30 lbs. and the front tires at 50 lbs. With 14″ street tires and the original spark plugs, 13.38 is truly respectable.

There’s more to the 1/4 mile time that makes a 426 so special. Find out more in my article, What Makes the 426 Hemi So Special.

  • Ford Torino Cobra with a 428 cubic inch
  • Chevy Chevelle SS with a 396.
  • Dodge Super Bee with a 383 cubic inch

If I could travel back in time I would become a writer for one of the car magazines. A dream job! (Jan ’69 Car and Driver)

All cars were equally geared (3.50-3.55, except the Cyclone which had 3.91s) with automatics to try and even out the playing field.

The Hemi Road Runner had the fastest 1/4 mile time with the Cyclone coming in 2nd with a 13.94.

The Hemi also had the best MPH by far, 105.14, with the Cyclone CJ 2nd again at 100.89 MPH.

If the Hemi had 4.10s to more evenly compare to the Cyclone’s 3.91s, the difference would have been even larger.

Some good quotes in the article about the 426 Hemi:

“What is it like on the street? Breath-taking. The Hemi Road Runner has more pure mechanical presence than any other American automobile”

“The exhaust explodes like Kraka-foa and the wailing howl of surprised air being sucked into the intakes turns heads for blocks”

Chrysler’s 426 Cu. in, hemispherical combustion chamber V-8 was never intended to quietly propel Imperials down the freeway/expressway/throughway/parkway or allow you to carry an extra lawn chair in the back of your Plymouth Fury Station wagon”

February 1969 – Hot Rod Magazine Featured 2 Hemi Cars

The difference between the automatic with 3.23s and the 4-speed with 4.10s is night and day.

Hot Rod stated:

“running with the 3.23 geared car…”is like running with one flat tire”

The 4-speed car actually came with 3.54 gears but the 4.10s were swapped in to make it faster. The car currently has the 3.54s back and the picture below shows how it is today.

Towards the end of 1968, Buddy Baker ran high speed tests with the Charger 500 equipped with the Race Hemi. He reached a top speed of 192.27 MPH.

Buddy said when he slowed down to 187 MPH things got boring.

It should have been against the law to install 3.23s with a Hemi. The gear ratio obviously hurts the 1/4 miles times.

Also, this car had a column shifter which leads me to believe they didn’t manually shift the gears and just left it in drive.

As noted by the Super Stock & Drag Illustrated ’69 Hemi Road Runner test above, leaving it in drive slowed the car by almost 1/2 a second.

426 Hemi 1/4 mile time and speed with automatic transmission and 4.10 rear gears:

  • 13.34 @ 107.52 MPH

The magazine was given two cars by Chrysler that day, a Hemi Road Runner and an almost identical Road Runner but with a 440 6-BBL (Six Barrel)!

They both had automatics with 4.10 gears and maybe the most menacing hood scoop ever made, the Air Grabber.

To achieve the best time with the Hemi, they did the following:

  • Lowered the tire pressure down to 32 psi
  • Replaced the spark plugs with a new set.
  • Removed the air filter.

It’s not a Hemi vs 6-BBL article but you’re probably curious what the 440 ran. Its best time of the day was 13.65 @ 102.62 MPH.

Here’s what they said about the two cars:

Whether the Hemi is worth the extra money and extra weight over the 440 6-BBL for three tenths and 5 miles per hour remains a question answerable only by the buyers of the 1970 Road Runners.

May 1970 – Hi-Performance Cars Magazine – 1970 Plymouth Hemi Cuda Convertible

426 Hemi 1/4 mile time and speed with an automatic transmission and 4.10 rear gears:

  • 13.40 @ 105.10
  • 13.45 @ 105 MPH
  • 13.50 @ 103.70
  • 0-60 MPH: 5.6 sec

Snap shots from Hi-Performance Cars magazine Hemi Cuda Road test.

They raced it against a Six Pack and said the Hemi took it by a few car lengths. Unfortunately, they didn’t provide more details about that race.

On the best of the three runs they drove the car out of the hole at near idle speeds, then nailed it. This seems to be a recurring theme throughout many of the magazine tests to try and prevent tire spin.

The writer also stated the spark plugs were original and the 2-3 transmission shift seemed to be very sloppy. This was due to the excessive beating the car was subject to from other magazine road tests prior to this one.

Hemi Cuda convertibles are one of the most expensive muscle cars out there. Find out the most recent prices of Hemis in my article, How Much An Original 426 Hemi Car is Worth: Recent Prices.

426 Hemi 1/4 mile speed and time with a 4-speed and 4.10 rear gears:

Unable to hook up properly off the line, what else is new, they changed the Polyglas rear tires to slicks. The 1/4 mile time and speed improved to the following:

  • 13.47 @ 105.88 MPH

A very respectable 1/4 mile for a bone stock engine in a car weighing 4,070 pounds.

An interesting part of the story is they went heads up with a 1970 GTO. It was equipped with a 400 cubic inch Ram Air IV with a 4-speed and 3.90 rear gears.

The GTO was rated 55 less horsepower and it showed as it was no competition what so ever for the 426 Hemi.

To get the best elapsed times they shifted the Hemi at 6,300 RPM.

The GTX was equipped with the Air Grabber scoop which was intimidating enough to win the race before it started.

Wrapping Up The 426 Elephant Engine

You’ve probably seen many videos online showing “stock” Hemi cars running a 11 second or low 12 second 1/4 mile. These cars aren’t factory stock.

The particular class they’re running in allows some modifications like compression. Also, some racers port the factory exhaust manifolds and heads to pick up horsepower.

Some racers employ some tricks of the trade (cheating) to gain every advantage possible. After all, it’s like a street race on the track.

What these cars do show all of us, is the potential a stock factory Hemi car does have with only a few modifications.

Heck, just throwing slicks on a factory Hemi car makes it light years faster. Check out more Hemi articles below!
