I kow this is an old thread, but since I've been searching for information on this very topic, and most info I found is here, I thought this might be the best place to add this :
From Barry's website
, we can see there are two versions of the dealership databook
(early and late). Some pages show a difference concerning the 383ci engine.
In the early version of the brochure, on page 21, the E63 engine code appears twice :
- Once for the 330HP version, optional on the base Challenger (N/A on the R/T),
- Once for the 335HP version, standard on the R/T (N/A on base Challenger).
In the late version of this page, only the 335HP version remains, as the standard R/T engine and the optional base Challenger engine :
To confirm this, in the engine lineup, pages 13 to 15, there are two distinct 383 4-barrels in the early version (383-4bbl and 383-4bbl Magnum).
The 383 Magnum is not available on base Challenger. Only the Magnum remains in the late version. The text description of both engines is identical, the only difference is their power outputs (330/335).
Early Page 13 :
Late Page 13 :
However, there might be some errors in the brochure, as the graphics (in both early and late version) show the 383 Magnum and the 440ci-4bbl using a single snorkel air cleaner :
Now the questions :
Does anyone know when the switch took place between the early and late versions?
If people with JH23N0B or JH27N0B Challengers can post their SPD and original engine color, maybe we can estimate this (or rather fins out when was the earliest orange 383 Magnum installed in a base Challenger).
Can anyone confirm that AC or export specs would somehow influence the engine used for a N code, E63 car?
