The above are tables of the estimates I have so far.
As time goes on, more and more cars will appear but I think the basic percentages we come up with for the various options
and combinations of options will hold up. The manner in which I arrived at the above numbers is detailed
below. Don't be appalled if three pages into this you ask: where is the booze? That
is the normal reaction to most statistical analysis as it is a guess at reality rather than a confirmation.

__NEXT STEP: Do you
have any pull with any of the other people who maintain lists of Superbirds? I understand the hesitancy
of people to share the data but if you know of anyone who would, please let me know.__
We may as well start with the engine.
The engine seems to be the single option of the most interest to people when they talk about muscle cars.
Thankfully, the Nascar Serial Number List exists to help us out. It really is an amazing document
to have at one's disposal. As you know, it lists 1920 cars and the VIN code conveniently carries an engine
designation code. I have only seen one car miss-coded and that was on the fender tag not the VIN so we
can make the reasonable assumption that the Nascar list is an accurate representation of the actual cars built.
One could make the case that the percentages we get from the Nascar list may not be accurate if cars were built that
did not appear on the list. Over the years the number of cars built has been reported to be anywhere between
1920 and 2000. I think we can safely conclude, given the extensive investigation of VIN discrepancies in
other documents disseminated earlier, that 1920 is almost exactly the number of street cars built. As you
know, cars framed or built for racing are another issue altogether.

The DSAC counting of the cars in the
Nascar list by engine is as follows:

440-4
1162 cars 1162/1920
60.52%

440-6
665 cars 665/1920
34.64%

426 Hemi
93 cars 93/1920
4.84%

We get the percentages of each engine option by dividing the actual cars with each engine
into the total cars. The results are above. I believe these results are more accurate
than those extrapolated from the surviving cars.

The surviving cars that I have on file show up in the
following numbers:

440-4
420 cars 55.48%

440-6
288 cars 38.05%

426 Hemi
49 cars 6.47%

We get the percentages of each engine option of the surviving
cars by dividing the cars with each engine into the total number of cars that we have data for - in this case, 757 cars.
The results are above. The strange numbers begin to show up when we try to find the total number
of cars originally produced with a given option based upon the numbers that survive today. As we discussed
earlier, Hemi cars have a way of surviving no matter what condition they are in and, therefore, will show up in a disproportionately
large number today compared to a lowly 440 4 barrel Superbird (humor intended here).

If we use the
surviving cars as an indicator of what was originally produced, we get the following:

440-4
420 cars divided by 757 equals 55.48 %
times 1920 equals 1065 cars

440-6 288 cars divided by 757 equals 38.05% times 1920
equals 731 cars

426 Hemi 49 cars divided by 757 equals 6.47% times 1920 equals
124 cars

If we compare these extrapolated numbers with the actual numbers known from the Nascar list
we see some significant differences. You and I both know that there is no way 31 Hemi Superbirds were built
that were not on the Nascar list AND have never shown up anywhere in the world. I also seriously doubt
there are 60 V code cars built that never show up on the list. And, we know from the list that there were
more than 1065 U code cars built.

At this point, one can legitimately ask; "if we can't extrapolate
forward with our surviving car numbers, what is the point"? I think the numbers we will extrapolate
will be reasonably representative of actual production percentages for options other than engines because those other options
don't really have much to do with whether a car survived or not. Did more automatics survive than manuals?
Probably a few due to the way people drive manuals more aggressively but I don't think transmission was a significant
deciding factor in the survival of a car. Would paint color make a difference? Maybe
a little. Red and orange are very aggressive colors and it is possible that people ran cars of that color
harder than the white cars but I don't think that would have a significant effect on survival rates. How
about seat style, interior color, wheel style or radio options? I seriously doubt those differences had
any effect of the survival of a car.

So with those caveats in mind, we can go forward with our estimation
of the various options and combinations of options that we believe to have been installed on Superbirds originally.

When people speak of the rarity of
a given car, they usually ask; "How many of this color with this engine and this transmission were built?"
To go much further is really splitting hairs. If one really wanted to stretch things, each car is
a one of one. There were very few absolutely identical twin cars built unless they were fleet vehicles.
With three engine options, seven exterior color options, two transmission options, two interior color options, two
seating options, four shifter/console options, five wheel options, three radio options, three tachometer/clock options, etc.
etc. etc., one sees that the number of possible combinations soon exceeds the total number of cars built. At
some point, every car becomes a one of one.

To answer the color/engine/transmission questions, let's
start with the relative rarity of each individual option and then get more complicated.

We already know
the engine rarity so let's turn to exterior color. To get these numbers, I sorted the data first according
to engine and then exterior color. A chart is actually the easiest way to display this data.

__Chart of engine and exterior
color option combinations - based upon existing cars:__
| 999 | EB5 | EK2 | EV2 | EW1 | FJ5 | FY1 | Totals |

U
CODE | 10 | 49 | 53 | 51 | 33 | 37 | 77 | 310 |

**Totals** | **18** | **88** | **90** | **103** | **110** | **63** | **147** | **619** |

This chart is a breakout of the 619 cars that I have engine and
exterior color data for. I have seen almost every color of car painted almost every other color so I think
we can discount any tendency to paint cars a given color skewing the data. The only exception to this would
be 999 or Petty Blue. It seems that people really like this color and an inordinate number have painted
and left their cars this color. Petty blue composes the smallest percentage of cars. Our
numbers should be close to what was originally produced.

What I am looking for here are the totals
at the bottom of each color column. This number divided into the 619 total will give us what I believe
to be an accurate percentage of each car painted that color. I am ignoring the burnt orange mistake cars.

__Chart of engine and exterior color option combinations percentages - based upon existing cars:__ | 999 | EB5 | EK2 | EV2 | EW1 | FJ5 | FY1 | Totals |

The percentage at the bottom of the columns can now be multiplied times 1920 to get an estimate of total cars built
in each color.

**Totals** | **56** | **273** | **278** | **319** | **342** | **196** | **456** | **1920** |

Note: the percentages in each square denoting a combination of
engine and exterior color are subject to the same variances as in the first example due to the inclusion of the existing car
engine data as a variable. The totals in red, however, should be a fairly accurate representation of production
totals. I know this gets a little confusing. There may be slight variations of each
exterior color/engine combination, but the overall percentages of each color should be close.

If we really wanted to, we could go
further and use the Nascar list percentages to reverse estimate the actual number of cars built with each engine and exterior
color combination by multiplying the engine percentage times the estimated total exterior color production. We
would find that there was actually very little variance however. For instance, the U code 999 would read
1.8%. The V code 999 would read .99%. And, the R code 999 would read .16%.
The greatest variance will be in the R codes because they have the highest deviation of surviving cars percentage from
production percentage. At this point, everyone's brain melts down…lol. But here
it is anyway. We start by inputting the percentage/estimated total production numbers in the bottom line
(Red). Then we put the known production totals of each engine from the Nascar list (Green).
Then we multiply the green percentage times the red estimate to get…… the (Blue) estimated production
of each engine and exterior color combination.

| 999 | EB5 | EK2 | EV2 | EW1 | FJ5 | FY1 | Totals |

U CODE | 34 | 165 | 168 | 193 | 207 | 119 | 276 | 60.52% |

V CODE | 19 | 95 | 96 | 111 | 118 | 68 | 158 | 34.64% |

R CODE | 3 | 13 | 13 | 15 | 17 | 9 | 22 | 4.84% |

**Totals** | **2.9%****/56** | **14.2%/273** | **14.5%/278** | **16.6%/319** | **17.8%/342** | **10.2%/196** | **23.7%/456** | **100%/****1920** |

The above chart,
given the data we have now, is probably the best estimate of number of cars produced with each engine/exterior color combination.

Another common question asked concerns the engine and transmission combinations.

__Chart of engine and transmission option
combinations - based upon existing cars:__ | Automatic
trans | Manual trans | Totals |

U CODE | 246 | 120 | 366 |

V
CODE | 107 | 127 | 234 |

R CODE | 20 | 20 | 40 |

Totals | 373 | 267 | 640 |

The above chart shows the breakout of the various engine and transmission numbers.
The Hemi cars seem equally split. The V code cars are surprisingly close and even more surprising
is that there appear to be more manual transmission six packs than automatics! It is the U code cars that
are really surprising with about a two to one ratio of automatics to 4 speeds. The overall percentages
are about 41.7% manual transmission and 58.3% automatic.

__Chart of engine and transmission option combinations
percentages - based upon existing cars:__ | Automatic
trans | Manual trans | Totals |

U CODE | 38.4% | 18.8% | 57.2% |

V
CODE | 16.7% | 19.8% | 36.6% |

R CODE | 3.13% | 3.13% | 6.25% |

Totals | 58.28% | 41.72% | 100% |

__Chart of engine and transmission combinations - extrapolation of existing car data to estimate actual numbers produced:__ | Automatic trans | Manual trans | Totals |

U CODE | 737 | 361 | 1098 |

V CODE | 321 | 380 | 703 |

R
CODE | 60 | 60 | 120 |

Totals | 1119 | 801 | 1920 |

Note: these figures are subject to the same variances as in the first example due to the inclusion of the surviving
car's engine as a variable. See the tendency for R and V codes to increase and U codes to decrease.

These numbers could be skewed slightly. The ratio of automatics to manuals could be even higher.
What?! Let's look at the percentages of surviving cars on file according to engine options.
Assuming that the 1920 production number is accurate, we have the following:

Engine
Nascar List
Prod. % Surviving
Surv %

440-4
1162 cars 1162/1920
60.52% 420
36.14%

440-6
665 cars 665/1920
34.64% 288
43.3%

426 Hemi
93 cars 93/1920
4.84% 49
52.69%

If one considers that most of the destroyed cars are U codes and there is almost a two
to one ratio of automatics to manuals in U codes, one can easily speculate that the actual percentage of automatics produced
was higher. More automatics than manuals would have been destroyed.

Again, all of this is contingent upon the accuracy of our data and the idea that very few cars were converted one
way or the other to a different transmission set-up.

Now let's go all the way with this.
Let's use the engine percentages that we know to be very accurate from the Nascar list and combine them with transmission
percentages of known surviving cars. If we use these numbers we can produce an overall percentage of automatics
to manuals. Here it goes:

| Automatic
trans | Ratio Au/Ma | Manual trans | Totals |

U CODE | 772/40.21% | 2.05/1 | 390/20.31% | 1162/60.52% |

V CODE | 304/15.84% | .84/1 | 361/18.80% | 665/34.64% |

R
CODE | 47/2.42% | 1/1 | 46/2.42% | 93/4.84% |

Totals | 58.47% | 1.41/1 | 41.53% | 100% |

After a little algebra we get the above chart. The significantly higher percentage of U code automatics
is slightly offset by the lower number of V code automatics. The overall percentage remains about the same.
For easy reference one can say that three out of five Superbirds had automatics. Personally I thought
it would be closer to two out of three but until I have more data, or find an error in the existing math, "about 60%
automatics" will have to be my answer.

OK.
So far we have the Nascar list to provide us with the total production number and the percentages for each engine option.
I believe these numbers to be very accurate. We have the surviving cars data to provide the overall
percentages of each transmission option and each color option. I believe these numbers to be reasonably
accurate. With all of this we can fill in the blanks of two tables - one for automatic cars and one for
manual cars. This will finally give us a set of answers for the "How many cars were built with a given
engine, transmission and exterior color?" question.

To get these answers, we take the total
cars of a given engine and exterior color and divide it up according to the automatic/manual transmission ratio that we found
earlier. For example: the 999 U code total is 34. The U code ratio is 2.05:1.
Therefore the number of U code automatics is 34 divided by (2.05+1) times 2.05 which equals 22.85 or 23 cars.
This leaves 11 manual transmission, U code, 999 cars.

**Totals** | **23** | **112** | **114** | **130** | **141** | **80** | **188** | **788** |

All these numbers should be considered within plus or minus one car of accuracy given the data we have.
This is especially true of the R code cars given the very limited production. I alternatively chose
to put the "extra" car in auto or manual table in order to keep the numbers sensible (no 1/2 cars).
