# How Rare is a 426 Hemi? The Rarest Hemi Car Models Produced

Many people like to talk about the rarity of a particular car model or engine option. This is especially true discussing the iconic 426 Hemi engine. How rare is a 426 Hemi?

**During the 426 Hemi’s production, only 0.7% of the car models which offered the engine as an option were produced with the 426 Hemi. **

- 13 car models, from 1966 to 1971, offered the street 426 Hemi as an option. Those 13 models produced a total of 1,396,755 cars. Only 9,778 of the total were produced with a 426 Hemi engine (.7%).

Those production numbers make the 426 Hemi pretty rare. This article breaks down the production numbers by car model for all years and each particular year. In addition, I’ll examine how rare a Hemi car is by percentage or frequency per every number of cars.

## How Rare is a 426 Hemi?

There is multiple different ways to measure the rarity of the famous Mopar engine. This article will focus on the total production and frequency of each car model. It doesn’t break down each model by transmission, color, hardtop, etc., only by Hemi engine.

I’ll examine each model by all years and each individual year the engine was produced. The article will include total numbers and percentages, including the rarity within each car model itself.

*Race Hemi engines and cars were not included.* The following statistics are for the street Hemi engine only. Check my article, 426 Hemi Production Numbers: Street and Race, for race Hemi stats.

## The Rarest 426 Hemi Car Models: All Years Combined

The following chart indicates the total number of each car model, starting with the rarest, produced with the 426 Hemi. It includes all years combined.

- The Dodge Charger 500 car model produced the least number of cars, 60, with the Hemi engine.

Vehicle Model | Quantity Produced With a 426 Hemi (1966-1971) |

Dodge Charger 500 | 60 |

Dodge Daytona | 70 |

Plymouth Superbird | 135 |

Dodge Challenger R/T | 427 |

Dodge Super Bee | 441 |

Dodge Coronet R/T | 633 |

Plymouth Belvedere | 683 |

Dodge Coronet | 746 |

Plymouth ‘Cuda | 781 |

Plymouth Satellite | 850 |

Dodge Charger R/T | 1,461 |

Plymouth GTX | 1,477 |

Plymouth Road Runner | 2,014 |

All Models | Total: 9,778 |

The top three very rare models in the list were only offered for one year. Of course this helped them top the list.

## Rare Car Models for One Year

- In 1968, the Dodge Coronet produced the least number of cars, 2, with the Hemi engine in any one year.

Vehicle Model | Least Number Produced With a 426 Hemi (1 Year Only) |

1968 Dodge Coronet | 2 |

1967 Dodge Coronet | 3 |

1967 Plymouth Belvedere | 6 |

1967 Plymouth Satellite | 6 |

1970 Dodge Coronet R/T | 14 |

1971 Dodge Charger R/T | 63 |

1969 Dodge Daytona | 70 |

## The Rarest Year for 426 Hemi Engines Produced

- The rarest year for cars produced with a 426 Hemi engine is 1971. A total of 356 was produced by all the car models.

The following chart indicates the number of Hemi engines produced in each year starting with the most uncommon (most rare).

Year | 426 Hemi Engines Produced |

1971 | 356 |

1967 | 1,136 |

1970 | 1,543 |

1969 | 1,724 |

1968 | 2,289 |

1966 | 2,730 |

All Years | 9,778 |

## The Rarest Percentage of Hemi Engines Produced for One Car Model

A rare Hemi car can be determined by a percentage (frequency) instead of total production numbers.

*Percentage and production figures are two different statistics. The lowest production car may not be the lowest percentage for its model, year or production run.*

One way to determine this is by examining one particular car model, year or for the six year Hemi production run.

For example, pick one car model (’66 Charger) offering a 426 Hemi option and determine how many of those cars were produced for the year (37,344). Divide the total number of Hemi engines produced (468) by the total number of cars produced (37,344) in the same year.

The answer is 1.25%. This means 1.25% of all Chargers produced in 1966 came with the 426 Hemi.

Here’s another way to look at it. Let’s say one hundred 1966 Chargers are lined up. On average you would find a Hemi approximately every 80 cars.

Even though the 1966 Charger had the least number of Hemi engines produced for the 1966 year, it didn’t have the least percentage. It was the ’66 Coronet which had the least percentage of hemi engines per every 100 cars, less than one. On average you’d have to line up approximately 338 Coronets before finding one with a Hemi.

The table below indicates the lowest percentage (frequency) of Hemi engines by total production number, per model, in one year.

- The 1968 Dodge Coronet only produced one 426 Hemi every 89,300 Coronet cars produced.

Year/Model | Total Quantity Produced | % of 426 Hemi Produced | Freq. of 426 Hemi |

1968 Dodge Coronet | 178,600 | .001% | 1 Hemi every 89,300 cars |

1967 Dodge Coronet | 149,583 | .002% | 1 Hemi every 49,861 cars |

1967 Plymouth Belvedere | 115,702 | .005% | 1 Hemi every 19,284 cars |

1967 Plymouth Satellite | 32,378 | .018% | 1 Hemi every 5,396 cars |

1970 Dodge Super Bee | 15,506 | .23% | 1 Hemi every 431 cars |

1970 Plymouth Road Runner | 41,484 | .37% | 1 Hemi every 273 cars |

1971 Plymouth Road Runner | 14,218 | .39% | 1 Hemi every 258 cars |

1971 Dodge Super Bee | 5,054 | .43% | 1 Hemi every 230 cars |

1966 Plymouth Belvedere | 151,124 | .44% | 1 Hemi every 223 cars |

1970 Dodge Coronet R/T | 2,615 | .53% | 1 Hemi every 187 cars |

## Percentage by Year: All Dodge and Plymouth Models Combined

The same frequency of Hemi engines (1 every number of cars) can be determined for each year.

This can be accomplished by using two figures. One, the total number of cars produced of every car model a Hemi was available in. Two, the total number of Hemi engines produced for the year.

The following table indicates the frequency, starting with the rarest, of Hemi cars for each year 1966-1971.

- 1967 is the rarest year for 426 Hemi engines produced per every hundred cars (Frequency).

Year | Total Quantity Produced | % of 426 Hemi produced | Freq. of 426 Hemi |

1967 | 335,747 | .34% | 1 Hemi every 296 cars |

1966 | 477,468 | .57% | 1 Hemi every 175 cars |

1968 | 278,121 | .82% | 1 Hemi every 121 cars |

1971 | 35,367 | 1% | 1 Hemi every 99 cars |

1969 | 155,011 | 1.1% | 1 Hemi every 90 cars |

1970 | 114,771 | 1.3% | 1 Hemi every 74 cars |

It’s interesting to note the percentage of Hemi cars by model increased in later years even though the overall production numbers decreased.

This is so because in the early years a Hemi could be ordered for a grocery getter. Grandma was likely to order a Coronet but not with a Hemi.

In the later years it was only available in the sport models. Therefore, somebody ordering a R/T would be more likely to check off the Hemi option.
