A66 Challenger Registry

Interesting data on A66 serial numbers and production plants from the A66 Challenger Registry;

Here is some data; What is interesting are the date codes in relation to serial numbers and order numbers against specific plant production.

The earliest SPD in the A66 Registry is an HOE car with a 9/29 date and SN starting with 108.
(Keep in mind that the A66 package was a late production decision and they did not become "formally" available until mid October 1969.)

The earliest A66 HOB car is dated 9/22 w a SN starting with 130, with heavy Hamtramck production in October, November and December.

Early serial numbers 108 though about 129 was all HOE (as per the A66 cars in Registry) September through December. 🤓

The last H0B hardtop listed is dated 708 w a SN starting with 421. The latest listed H0B vert is dated 622 with a SN starting with 390. 🤓

The question of the use of 340 hood decals vs the metal callout emblems continually comes up as a question about their usage on Mopar sites. Just some thoughts on this

if you are unfamiliar. The A66 package was a late addition to the 70 Challenger lineup. Ma Mopar originally planned to not offer the 340 in the Challenger. The A66 package was not formally available until October. No metal 340 callouts were available yet and the decals were quickly made as callouts and used in production September/October through about December when the metal emblems finally became available.
The 340 decals had a factory part number.

A66 Challenger vert from the Registry Archives. Nice color combination. Anyone own this one?

thought about this over the weekend 

all 1970 Challenger R/Ts (JS) have the "sport" hood with engine callout emblems - someone mentioned these hoods would be pre-pierced with holes for the emblems (all in the same locations & spacing)

late to the party, along comes the A66 340 engine package for the base Challenger (JH) - the emblems are not ready yet and stickers have a shorter lead time, so Dodge puts in an order for stickers
BUT - now Dodge needs a hood without the pre-pierced emblem holes, so Dodge puts in an order for "sport" hoods without emblem holes

could the flat hood 340 cars exist because the assembly plant randomly ran out of the now needed "sport" hoods without emblem holes early in the model year because there was a limited supply

Bob, the 4 barrel 70-71 340 used a non restrictive (no extensions) air cleaner with opening on both sides,

Thank You

Does anyone please know if the A66 was referred to as a 340 Scat Pack?  It wasn't mentioned in the 1970 Scat Pack brochure but it had the decal of the rear quarter windows.

Color Percentages of EW1 A66 Challengers listed in the A66 Registry; A member of a forum wanted to know how many A66 Challengers were in the A66 Registry that are EW1 white;
As per the Registry; There are a total of 6 original EW1 A66 Challenger hardtops in the A66 Registry. 1 with a blue interior, 2 black, and one red. (2 unknown color interiors)

4.2% of all JH23 V-8 Challengers (includes 318 and 340 cars) were EW1. If you take 4.2% of 340 Challenger production of 6399; there would be a total of 291 A66 Challengers produced in this color, as a rough estimation.

Another inquiry about how many FK5 A66 Challengers are in the Registry;

Currently, there is a total of 25 FK5 A66 Challengers in the Registry.
17 automatics, 6- 4 speeds, and 1- D13 3sp.
Interestingly, 14 of these A66's have the H6K4 interiors.
9 have the black X9,
1 with white and 1 with the vinyl/cloth H6K4.

This is out of a total of 235 A66 Challengers in the Registry (with and full or partial data).
Again FK5 was 10.1% of ALL JH23 V-8 production and 9.5% of all JH27 V-8 production. Take the total color percentages for what they are worth!
